Choosing the right subjects and entering the correct syllabus codes matters. A wrong code at registration causes processing delays and stress.
Foreign passport holders follow a shorter rule. They need five subjects only, without the local compulsory papers.
This guide lists the compulsory subjects and the electives by stream with their Cambridge codes.
How Many Subjects Do You Take at O Level?
Pakistani national students take eight subjects for equivalence. That means five compulsory papers plus three electives chosen by career direction.
Students can enter more than eight if they wish. IBCC then counts the best eight, which must include all five compulsory subjects.
Foreign passport holders need five subjects only. English and Mathematics stay compulsory, and the local papers do not apply.

Which Subjects Are Not Available at O Level?
A few subjects families expect are simply not offered at this stage. Planning around them saves a wrong entry.
- Psychology and Law: Cambridge does not offer these at O Level. Both are available at A Level only.
- Commerce: Commerce (7100) exists at O Level only, with no A Level equivalent.
- Foreign candidate rule: Foreign passport holders are exempt from Islamiyat, Pakistan Studies, and Urdu.
Do Your Subjects Decide Your IBCC Group?
Yes. Your three electives fix your IBCC group, which decides the degrees open to you later. Science electives secure the science group, and business or humanities electives place you in the arts group.
Picking the right combination for a career is a separate decision with its own steps. The full framework, by career path and with the common mistakes to avoid, sits in the guide on how to choose O Level subjects.
