Hello Vinayak,

Yes, as per JoSAA (Joint Seat Allocation Authority) and JEE Mains/Advance eligibility criteria , the subjects considered for calculating the top 20% percentile or the minimum qualifying marks for General Category are:

1. Physics
2. Chemistry
3. Mathematics
4. One language subject (like English)
5. One additional subject (can be any subject except vocational ones)

In your case, Geography can be considered as the fifth additional subject , which is allowed under JoSAA rules. So, if you're calculating your score using Physics, Chemistry, Mathematics, English, and Geography and getting exactly 378/500 , it should be valid for both JEE Mains and JEE Advanced eligibility, provided all other criteria are met.

Make sure to double-check the official JoSAA counseling guidelines or updates in case of any changes in the rules.

I hope this answer helps you. If you have more queries then feel free to share your questions with us we will be happy to assist you.

Thank you and wishing you all the best for your bright future.
