Help needed regarding bitsat criteria

My Current Standing:

Cleared the >60% individual criteria in Physics, Chemistry, and Maths in my main 12th boards.

2. My original PCM Aggregate was 24 marks short of the 75% cutoff.

3.Took the July Improvement exam for Maths (+17 marks gained), but I am STILL 7 marks short of the 75% aggregate requirement.

*Considering if I reappear for board next year to cover that 7 marks deficit.

Will BITS accept 3 marksheets during document verification?

Should I re-appear for 1 subject (Chem) or 2 subjects (Phys + Chem) next year to cover that 24 marks assuming 3 marksheets are rejected and my July Maths marks can't be used alongside a third sheet
