Abstract This study purported to identify major factors which influence perseverance in studies at a distance teaching university with an open admission policy. The results indicate that: students who study in organised groups and get weekly tutorials have a higher perseverance rate as compared to students who study in the regular framework which provides tutorials every three weeks; veteran students have a greater chance to complete courses successfully as compared to novice students; and the success rate in liberal arts and social science courses is considerably higher as compared to natural science and mathematics courses. On the other hand, the factors of age, sex and previous level of education do not have an impact on perseverance and success in studies.
