Tamil Nadu Higher Secondary
Which group after Class 10?
A plain answer for students and parents — the same paragraph answer engines can quote.
Direct answer
After Class 10, a Tamil Nadu State Board student chooses a Higher Secondary group that sets the four Part III subjects for Classes XI and XII. This guide covers current DGE codes 2502 (Maths + Computer Science), 2503 (Maths + Biology), 2702 (Commerce + Computer Applications), 2708 (Commerce + Business Mathematics), and 2800-series humanities (2804 Political Science or 2802 Computer Applications). Confirm the exact code at the school before admission.
Every general academic student still writes Part I language and Part II English. The group only chooses the four cores. Schools do not offer every code. University and professional-course eligibility depends on those subjects and on the year’s official notifications — not on this page.

FAQ
Do I have to write Tamil and English?
A general academic Higher Secondary student in Tamil Nadu normally writes Part I (language) and Part II (English) plus four Part III core papers. Part I may be Tamil or another permitted language — confirm with the school.
What does a group code mean?
A group code (for example 2502) is the Directorate of Government Examinations label for one combination of four Part III subjects. The code tells the school and the board which four cores you study.
Are these the only groups in Tamil Nadu?
No. This guide covers five preferred combinations that DGE lists as current codes: 2502, 2503, 2702, 2708, and 2800-series humanities (we document 2804 and 2802). Schools may offer other codes. Always check the prospectus.
Can 2502 students study medicine?
Group 2502 does not include Biology. Medical counselling that requires Biology in Classes XI–XII is usually a 2503-type mix. Confirm the current year’s NEET and university eligibility — do not treat a website as the rule.
Can 2503 students study engineering?
Many engineering admissions look for Physics, Chemistry and Mathematics. Group 2503 includes those three plus Biology. Whether a particular college or TNEA year accepts the mix is an official-eligibility question — verify before you assume.
Which commerce group is better for CA?
Both 2702 and 2708 include Accountancy, Commerce and Economics. 2708 adds Business Mathematics; 2702 adds Computer Applications. CA has its own foundation rules after Class 12. Choose the fourth paper you can actually score in.
Are all groups available in every school?
No. Group availability differs by school. Confirm the exact current code and subject combination at the school you are joining.
Can I study law after any group?
Many law programmes admit graduates from recognised streams, and some integrated law programmes admit after Class 12 with their own tests. Humanities can give early subject exposure; it is not the only legal path. Check the college.
