This study explores factors contributing to academic success of 382 full time diploma students at Faculty of Business Management in a public university in Sarawak. The study lasted eight semesters (four years) from June 2012 until April 2016. The instruments comprised questionnaire, analysis of final examination results and detailed information from student registration database. Pearson bivariate correlational analysis showed that there was a significant relationship between students' CGPA and their fathers' monthly salary (p<0.01) and their mothers' monthly salary (p<0.05). However, there was no significant relationship between students' CGPA and number of siblings in the family. Findings indicated females outperformed their male counterparts in studies. Additionally, there was a significant difference in the mean CGPA among different races of students (p<0.01).
