Successful achievement in any form of activity is based upon study, interpretation and application (Yoloye 1999); and that study should have a purpose. It therefore depends on individual to decide why he or she wants to study, either to gain new ideas or to find out relationship between two differ-ent things. What one learns as a result of study depends on the degree at which one succeeds in achieving that aim or purpose. As one studies, it is possible, of course to value other than one’s primary desire at the moment. Isangedighi (1997) reports strong correlation between study habits and academic achieve-ment of high school students. The importance of study skill training as a com-ponent in test-anxiety treatment programme was demonstrated by Abba1) and in another study by Tukur & Musa (2001). These researchers concluded that “a reduction in test-anxiety is no guarantee of subsequent improvement in ac-ademic performance when the level of study habit competence is ignored”. Some researchers have found note taking activity as study habits variable to be beneficial to students. While Abba1) and Tukur & Musa (2001) found that note taking leads to overall superior performance and retention of new materi-als. Several investigations have suggested that less skilled reading is charac-terized by a limitation in short-term memory capacity in addition to inefficient word-identification (Isangedighi, 1997; Yoloye, 1999). But according to (Fagbemi, 2001) the degree of learning depends on the amount of time the child is actively engaged in learning. The time spent on studying helps stu-dents to retain the materials learnt, which will eventually boost the students’ performance outcome during tests or examinations. Therefore, this study in-vestigates the relationship between undergraduates’ study habit and their aca-demic achievement.
