Dear Ruma,

Basic eligibility criteria to appear for NEET exam is as follows:

• You should have passed your class 12 qualifying exam with PCB combination  from any recognized board
• For OBC - min qualifying percentage must be 40% (aggregate)

So, if you have obtained 46 marks in physics at your 10+2 level but your aggregate marks in PCB is <40% , then you are not eligible .
