Hi

hope you doing well

Since your Maths is an optional (6th) subject, and its marks are not included in your overall percentage, here’s how you can report your class 12th marks:

For JEE Mains:

• If you're applying for a course that requires Physics, Chemistry, and Mathematics (PCM) (like engineering or fire engineering at NFSC Nagpur), the focus will be on your PCM subjects.

• If Maths isn't included in your overall percentage, you can use the following combination for your class 12th percentage: Physics + Chemistry + Biology + English + Physical Education
  (PCB + Eng + Phy Ed)

  Recommended

JEE Mains primarily requires your PCM subjects if you are applying for engineering courses. However, the final eligibility may only look at Physics and Mathematics marks for verification, even though the overall percentage might exclude Maths.

If you are opting for PCB-based courses, your Biology marks will be taken into account instead of Maths.

Hope this will help you

Best Wishes.
