Choosing A/L subjects is the first real decision on the road to university, because many degree programmes accept only certain subject combinations. This guide shows the subject requirements published by the University Grants Commission (UGC) for some of the main course groups, so you can match your subjects to the courses you want.
Medicine, Dental Surgery and Veterinary Science
The UGC document lists at least an “S” grade in each of three subjects: Biology, Chemistry and Physics.
Engineering
At least an “S” grade in each of Chemistry, Combined Mathematics and Physics.
Biological Science degrees
At least an “S” in Biology and Chemistry, plus one of Agricultural Science, Higher Mathematics, Mathematics, Combined Mathematics or Physics.
Physical Science degrees
At least an “S” in three subjects, including Combined Mathematics or Higher Mathematics, and Chemistry or Physics.
Management and Commerce
One route listed is Business Studies, Economics and Accounting. The document also allows a mix of two subjects from that group plus a third from a wider list. Courses differ, so read the exact rule for each degree.
Law
The document lists a choice of subjects such as Economics, History and Business Studies, and notes a Credit (C) pass in English at O/L.
Computer Science and IT
A Credit (C) pass in Combined Mathematics, Physics or Higher Mathematics, with S passes in two further approved subjects.
How to use this when choosing your stream
- Decide on two or three target courses first, then check their prerequisites.
- Remember that most selection also needs at least an S in all three subjects in one sitting and a minimum of 30% in the Common General Paper, as stated in the UGC handbook.
- Keep a realistic backup course that accepts your combination.
For help weighing the streams, read how to choose your A/L stream. After results, see how university admission works and how the Z-score works.
Frequently asked questions
Can I switch courses if my subjects do not match? The prerequisites are conditions for being considered for a course, so a mismatch generally means you cannot apply to it. Check the handbook.
Do these rules apply to private universities? No. They are UGC rules for state university admission. Private institutes set their own entry requirements.
