Group codes, subject combinations, and undergraduate eligibility change — confirm the current offer with the admitting school and official admission notifications before you decide.

Both codes include Physics, Chemistry and Mathematics. 2502 adds Computer Science. 2503 adds Biology. Language and English still sit on the timetable.
Choose 2502 when you care more about computing and you are comfortable leaving school Biology. Choose 2503 when you want Biology in the mark sheet and you can carry maths plus life science together.
Do not invent a rule such as “2502 students cannot write NEET” unless the current official notice says so — and then quote that notice. What we can say without a circular: 2502 does not teach Biology as a core.
Quick contrast
- 2502 — stronger school computing paper; usual engineering / IT conversation
- 2503 — Biology present; usual medical-adjacent conversation plus maths-based science
- Workload — 2503 is typically heavier because both maths and Biology are present
