AptitudeHub: A Centralized Platform for Free Aptitude Skill Development

In the modern educational landscape, aptitude skill development is critical for competitive exams, recruitment processes, and academic evaluations. However, current platforms are either financially inaccessible or lack a centralized and interactive approach. AptitudeHub aims to address these gaps by offering a free, locally hosted platform focusing on abstract reasoning, critical reasoning, and quantitative aptitude. It integrates features like interactive quizzes, performance tracking, and curated video tutorials to enhance learning outcomes. The platform is developed using the MERN stack, ensuring scalability, data privacy, and user-centric design. This paper reviews related works and presents a comparative analysis of the proposed system with existing solutions, highlighting its contribution to democratizing education

Salary Prediction for Computer Engineering Positions in India

Over the subsequent 20 years, India's economy has seen growth in many areas since the 1990s. Information technology is one of the industries that has grown significantly recently. Bharat's transformation from a sluggish economy to one of the top exporters of information technology services has been largely attributed to the information technology sector. Since there was such a huge need for skilled workers in the labor markets as a result of this boom, engineering has consistently ranked among the top high school courses of study. Additionally, engineering is a popular course of study due to the income potential and opportunity to progress technology. The primary compensation factors for recent engineering graduates in the Bharat Labor Markets are the focus of this study. The investigation looked at how factors like as demography, academic success, personality traits, and test scores affected starting pay. The analysis' findings showed that the significant predictors of starting pay were academic success at the faculty level, faculty name, college affiliation, and engineering major. The results also revealed that psychological characteristic skills, such as English and quantitative aptitude, as well as a desire to strive and complete a task well, are significant contributors to the starting pay of engineering graduates in Indian Labor Markets. This study used a machine learning method to carry out regression analysis. These procedures used the Naive Bayes, Random Forest, and Support Vector Machine algorithms (SVM).

Perceptions of gender norms and sex-typed cognitive abilities among Indian adolescents – A study of Andhra Pradesh and Telangana

Adolescents' sex-typed cognitive ability is said to be shaped by gender norms and gender roles. Gender discrimination is displayed in every sphere given the persistence of conservative societal values in India. This study used data from the most recent round of the Young Lives survey to investigate the impact of gender norms and gender stereotypes on sex-typed cognitive abilities in quantitative aptitude, receptive vocabulary, and reading ability among Indian adolescents living in the state of Andhra Pradesh and Telangana. As regards perception of gender norms, girls were more in favour of egalitarian society as against boys in favour of masculinity in the society. Boys outperformed girls in quantitative aptitude and receptive vocabulary when the effect of gender stereotypes and other socio-demographic influences on sex-typed cognitive abilities were controlled. Wealth status of household, educational qualification, medium of instruction and the perception of masculinity were found to have significant bearing on all three types of cognitive ability. Such a difference in cognitive abilities favouring boys call for an emphasis on promoting girls’ education in terms of quality and avoiding gender stereotype in the educational environment.

Importance of English Language In Competitive Examinations : An Awareness Stduy

Competitive Examinations are held to examine the IQ, the Logical Quotient and the Analytical Understanding of the candidate. Generally all competitive examinations have few subjects in common like Quantitative Aptitude, Logical Reasoning and English Language. English is a language that is widely spoken and understood by people all over the globe. Being one of the most commonly used languages, English has occupied its place in competitive examinations in order to understand the reading, writing and understanding skills of candidates. Communication skills of a person are evaluated partly on the marks scored in paper of English Language in the various competitive examinations. Most of the educational institutions today have designed their curriculum where English is taught and learned as first language and mother tongue becomes the second language. This is a small example to prove the importance of English in our education system as well as well as our careers. When people sit for competitive examinations either for further studies or for various government or private jobs, English is an unavoidable paper. This somehow depicts the importance of English Language in various Competitive Examinations. Proper use of the language is also regarded as a skill developed with continuous practice and learning techniques. Learning English and gaining a fluency in the language widens the career prospects.

IMPORTANCE OF LIFE SKILL DEVELOPMENT AND PLACEMENT SCENARIO POST COVID19

As a part of Life Skills Development, the students should be trained in various fields of personality development and communicational skills. The trainings can be imparted on Quantitative Aptitude, Verbal Ability, Mock Group Discussion, Mock PI and skill development in technical domains. Students should be encouraged to attend the training programs to upskill their performance in the campus interviews. Students should be hand hold through career guidance; motivational activities, counselling, knowledge sharing activities and by various capacity building measures. The trainees should be closely monitored for improvements and gauged through several practice sets. Due to pandemic COVID-19, companies have been scrapping interviews. It is to be expected that 60-65 per cent interviews would get dropped or delayed due to lockdown in many parts of the country and people are encouraged to stay at home to curb the spread of the virus. The overall hiring sentiment in the country is likely to witness an adverse impact in the short term with 60-65 per cent interviews getting postponed, especially in the services sector, following the slowdown across industries triggered by the coronavirus pandemic.Vision 2020: To empower the students with pre-placement training so that they get employed, which helps the institute/ university to boost its brand image? A thorough discussion on the importance of Group Discussion during placement, Assessment parameters during placement, Verbal and Non verbal communication to have a successful GD round and Do’s and Don’ts in participating in a Group discussion round has been dealt with. The importance of the rules to write a resume and Frequently Asked Questions in an interview during placement drives has been discussed.

Aptitude measures in SLA

Abstract The present study examines a US Department of Defense (DOD) foreign language program using linear and logistic regression to model foreign language proficiency growth over three time intervals. The analysis demonstrates growth from start to finish for a program involving domestic immersion and study abroad and tests the ability of aptitude and achievement measures to predict that growth for a group of 80 students. The findings suggest that a measure of foreign language aptitude and a measure of quantitative aptitude differentiate learning outcomes for the intensive domestic immersion portion of the program while measures of quantitative aptitude and native language verbal aptitude differentiate later-stage learners on the study abroad portion of the program.

QUANTITATIVE APTITUDE AMONG HIGHER SECONDARY STUDENTS

The present study is a survey in nature to find out quantitative aptitude among higher secondary students in Madurai District. The investigator in order to find out quantitative aptitude among higher secondary students developed and validated a tool for the study. The investigator followed stratified random sampling method for the study. Data were collected from the sample. The data were given appropriate statistical treatments. The findings of the study reveal that the majority of higher secondary students (54.22%) are at average level of quantitative aptitude. In differential analysis, there is significant difference in level of quantitative aptitude among higher secondary students in terms of sex. The male students are having more level of quantitative aptitude compared to their counterparts. But there seems to be no significant difference in quantitative aptitude among higher secondary students in terms of locality.

Academic Performance and Admission Criteria in a Graduate Business Program

The study evaluates a graduate business program by examining the academic performance of its students and its admission procedures using a sample selection model. It is shown that successful academic performance in the University of the Philippines’ graduate business program can be explained by past undergraduate performance and the quantitative aptitude test score. Other abilities revealed by test scores in reading and logic that are used as bases for admission to the program do not seem to have a bearing on performance. Hence it is possible that altering the relative weights of the three test scores will change the profile of successful applicants and at the same time improve the overall performance.

A new approach for assessing college students' improvements in quantitative aptitude

With the ethnic and cultural diversification of college students, quantitative reasoning aptitude remains as one of the fundamental capabilities that the students should acquire. This article presents a new method for assessing the improvement of college students in quantitative aptitude. The assessment test consists of randomly selected SAT questions. The test scores are compared with the SAT scores of participating students for statistically assessing students' progress in quantitative capabilities. The new approach does not require a pre-test. It is flexible, convenient to implement and statistically valid. It can also be used for continuous assessment of a college curriculum if the assessment test is given annually. This article also presents a pilot implementation study. The results show that material advantages may be derived from using this approach in assessing students' improvements in the quantitative aptitude.

Physics Intentions and the GRE

In the early 1980s, three coauthors and I published a letter ( Physics Today, Physics Today 0031-9228 37 4 1984 15 https://doi.org/10.1063/1.2916188. April 1984, page 15 ) stating that the Graduate Record Examination (GRE) aptitude tests showed that those students taking the tests and indicating physics as their intended area of study had the highest combined quantitative and verbal scores of the 98 disciplines listed. In view of evolving trends in graduate education, it seemed of interest to reexamine the quality of students planning to go to graduate school in physics, as measured by the GRE aptitude tests.The data given here appear in the GRE Guide to the Use of Scores, available online at ftp://ftp.ets.org/pub/gre/992362.pdf, and are based on exams taken between 1 October 1997 and 30 September 2000. Test takers were grouped into 50 broad fields by intended graduate major, and mean scores are reported for each of the three aptitude tests, verbal, quantitative, and analytical.For the physics and astronomy category, the mean score ranked first in quantitative aptitude, first in analytical, and tied for sixth in verbal (students who listed philosophy as their intended course of study ranked first in verbal aptitude). When the means are aggregated, students intending to study physics and astronomy easily rank first among the 50 categories. Physics graduate programs are still getting good students—so good, in fact, that the aptitude tests are of limited value in predicting first-year grades in graduate school, the one outcome for which complete data are published. The correlation of first-year graduate grades with the aggregate aptitude score is only 0.20. Moreover, the best correlation is with the verbal score, which is a little surprising until one notices that the standard deviation is largest for this test. Overall, the scores are so uniformly high that they provide little discrimination.The situation is somewhat different with the subject matter test: The correlation with first-year graduate grades is 0.27, about the same as for undergraduate grades, where the correlation is 0.28.© 2002 American Institute of Physics.

The effects of social anxiety and social skills on academic performance

This 2-year longitudinal study examined whether social anxiety, social skills, and other academic variables affect college grade point average (GPA) and academic persistence. First-year students ( n=253) provided baseline data. Those who reported emotional control (e.g. hiding emotions) were less likely to persist. For GPA over the first 2 years of college, predictors included social skills, institutional commitment, academic and social adjustment, high school class rank, quantitative aptitude scores, gender, and ethnicity. Emotional control became a significant predictor of lower GPA by the third semester. Those with higher college adjustment scores, higher class ranks, higher quantitative aptitude scores, and female gender were more likely to earn higher GPAs. Social anxiety did not emerge as a significant predictor of college persistence or GPA.

Working memory, short-term memory, and general fluid intelligence: a latent-variable approach.

A study was conducted in which 133 participants performed 11 memory tasks (some thought to reflect working memory and some thought to reflect short-term memory), 2 tests of general fluid intelligence, and the Verbal and Quantitative Scholastic Aptitude Tests. Structural equation modeling suggested that short-term and working memories reflect separate but highly related constructs and that many of the tasks used in the literature as working memory tasks reflect a common construct. Working memory shows a strong connection to fluid intelligence, but short-term memory does not. A theory of working memory capacity and general fluid intelligence is proposed: The authors argue that working memory capacity and fluid intelligence reflect the ability to keep a representation active, particularly in the face of interference and distraction. The authors also discuss the relationship of this capability to controlled attention, and the functions of the prefrontal cortex.

Some contributions to sex differences in scholastic aptitude scores

In this study no significant direct effect of sex on performance on ASAT was found. Further, sex differences in performance were found to be the result of females having a higher verbal ability as measured by English assessments, males studying more mathematics, and males having a greater confidence in success on ASAT. For this sample it was found that the female students achieved about 0.40 score points on ASAT more than males, after regressing out father's occupation, English assessment, hours spent studying mathematics, and confidence in success. The adjustment to ASAT scores in 1983 would certainly account for the positive effect of sex; i.e. being a female increased a student's score by 0.40 score points. After allowing for this adjustment of approximately 1.0 score points, being a male increased a students ASAT score by 0.60 score points. ASAT was found to favour students who scored well in English and those students who studied more hours of mathematics. English, in part, tests verbal aptitude and consequently it might be expected that there would be a significant positive effect related to English assessment. The number of hours of mathematics studied is not itself a direct measure of aptitude and consequently it may be considered that the number of hours of mathematics studied provides an advantage for performance on ASAT. However, it is not unreasonable to expect that it is those students of greater quantitative aptitude who would study more mathematics. The significant mathematics hours effect may be a result of this, since there is no control for quantitative aptitude within the model. It was, however, the very large effect which the score on the confidence in success attitude scale had on ASAT performance that was the most suprising. For some undetermined, perhaps social, reason, females had a significantly lower confidence than males. The relationship between Confidence in Success and performance might be expected since, in part, the Confidence in Success variable measures how well students thought they did on ASAT. It is still clear however, that after confidence in success is taken into account, sex has no significant effect on ASAT score. The predictors of success are English ability, hours spent in the study of mathematics, and confidence.

An investigation of online searcher traits and their relationship to search outcome.

This study investigated more attributes of online searchers that were believed to affect the quality of their search results. Subjects were selected from the online searching courses in six library schools. The searching proficiency of the subjects was measured by their performance on two DIALOG searches. Their creativity level was measured using two self-report inventories; their intelligence level was approximated from their GRE Verbal and Quantitative scores; and their personality traits in regard to masculinity, femininity, and self-esteem were measured using the Interpersonal Disposition Inventory. The large number of independent, predictor variables were reduced by factor analysis and the derived factors were related to the dependent variable, online searching performance, in a multiple regression analysis. The findings suggest that differences in searching performance can be attributed, to a small degree only, to general verbal and quantitative aptitude, artistic creativity, and to an inclination toward critical and analytical creative thinking. The findings also raise doubts, however, that high intelligence and other attributes cited by writers in the field are necessary for high performance. The notion that searching performance can be predicted by or is dependent upon certain cognitive or personality traits has thus become highly suspect.

Indicators of Success: Queens College Department of Library Science

This paper measures the relative power of various predictors of success in library school defined by receipt of the M.L.S. degree and graduate grade point average. Data concerning applicants accepted to the Queens College Department of Library Science in 1972 were analyzed statistically. It was found that the year in which the student's undergraduate degree was received was both a good predictor of success and important in evaluating other indicators of the student's potential. For example, multiple regression analysis suggested that substantial undergraduate grade inflation should be taken into account when considering applicants. Likewise, for pre-1968 college graduates, the quantitative aptitude score of the Graduate Record Examination was a significant predictor of success.

Attitude-Aptitude Relationships in the Quantitative Domain

The purpose of this study was to investigate the relationships among nine measures of attitude toward quantitative concepts and verbal and quantitative aptitude. Subjects were 353 graduate students enrolled in educational research courses. The attitude measures consisted of nine factor scores drawn from a seman tic differential instrument; the aptitude measures were the Graduate Record Examination Verbal and Quantitative scores. Canonical correlation was used to relate the attitude to the aptitude measures. Two significant canonical variates were obtained. The first showed a moderate relationship between positive attitudes toward quantitative concepts and high quantitative aptitude. The second indicated a slight relationship between negative attitudes toward quantitative concepts and high verbal aptitude.

Attitudes of Nigerian Secondary School Children to Programmed Instruction in Geography

Summary This paper reports an investigation into the attitudes of 200 mixed secondary pupils from both rural and urban schools towards programmed instruction as a teaching method and towards geography, as a subject studied in this way. Pupils in their second year in each school were divided into experimental and control groups matched on the basis of achievement, verbal and quantitative aptitude tests. The attitudes of both groups towards geography and programmed instruction were pre‐tested by questionnaire. The groups then underwent two different learning sessions for three weeks. Despite more positive attitudes shown initially by the control group to both geography and programmed learning, the experimental group later performed better and showed more favourable attitudes towards map reading than those taught by conventional texts, this being even more so for boys. Reasons for the results and certain features of the study are discussed.

Dimensional commensurability and cue utilization in comparative judgment

In a series of five experiments, subjects compared pairs of students with respect to potential college GPA. Both students had scores on one common dimension (e.g., English Skills) and one unique dimension (e.g., Quantitative Aptitude for Student A and Need to Achieve Success for Student B). The results indicated that dimensions were weighted more heavily in the comparison when they were common than when they were unique. Cautioning subjects not to increase the weight of the common dimension did not reduce the effect, nor did “correct answer” feedback with rewards for accuracy. In addition, the effect was substantial whether or not the common and unique dimensions had equal means and standard deviations. The results are congruent with a growing body of research that documents man's limitations as an information processor.

Category width and decision making in perception.

The cognitive dimension called category width may be related to decision-making behavior in the following way: broad categorizers tend to make more Type I errors while narrow categorizers are more inclined to make Type II errors. This contention was investigated using measures of decision-making performance on an auditory detection task. No correlations obtained between category-width measures and decision measures for 43 female Ss. However, for 38 male Ss, the correlation between category-width score and Type I error rate was significant as predicted. The correlation between category-width scores and over-all correct decision rate was also significant. A substantial relationship was also found between quantitative aptitude and category-width scores and factor scores for the two category-width factors for males. For women, quantitative aptitude did not seem to be related to category-width measures.
