CoViD-19 had a detrimental impact on all humans in our society, from white-collar office workers to students. The outbreak caused stress in all individuals, leading to pres- sure, and a decline in learnability, even though its magnitude and origins varied. In con- text with the education domain, the students have suffered adverse repercussions due to the shift from traditional in-person classes to online learning modes, which has been a major cause of their mental health’s downward spiral, leading to poor performances, and the inability to learn in unmonitored classroom conditions. Aim. To assess the stress in high school students and correlate their stress levels with their end-of-year examination results for 2021. Method. This can be achieved using Pearson’s correlation coefficient, by assessing 78 high school students selected as per inclusion and exclusion criteria, from the public schools of Hanoi, with their respective results obtained for their end-of-year examina- tions of March 2021. The Academic stress will be calculated with the Student Academic Stress Scale (SASS), and, all the percentage of grades will be out of 100. Results. The results obtained from the following Pearson’s correlation coefficient tests showed a moderate negative correlation existing between Academic Stress levels and marks it obtained, with the r value of -0.447. Limitations: The sample was collected from 4 public schools in Hanoi, not taking the rest of the country into account, and the accuracy of the stress level grading using SASS which can be affected by an impairment in cognitive function, excludes outliers from the research that was conducted.
