Study skills play an important role in influencing academic performance of university students. These skills, which can be modified, can be used as an indicator on how a student would perform academically in his course of study. The purpose of the study is to determine the study skills profile among Universiti Selangor's (Unisel) students and to find the relationships of these skills with student's academic performance. A sample of seventy-eight (78) foundation studies and diploma students of Unisel were selected to participate in this study. Using Study Skills Inventory instrument, eight skills were measured. They are note taking; test taking; textbook study; concentration and memory; time management; analytical thinking and problem solving; nutrition; and vocabulary. Meanwhile, student's academic performance was measured through their current Grade Point Average (GPA). The result showed that vocabulary skill scored the highest mean with 3.01/4.00, followed by test taking (2.88), analytical thinking and problem solving (2.80), note taking (2.79), textbook study (2.58), concentration and memory (2.54), time management (2.25) and nutrition (2.21). Correlation analysis showed that test taking (r=0.286, p=0.011), note taking (r=0.224, p=0.048), and analytical thinking and problem solving (r=0.362, p=0.001) skills were positively correlated with GPA achievement.
