Dear Aspirant

Hope you are doing well

It's  ok even if you have failed in maths but  you passed in your class 12th board examination with five subjects.

I am considering that you are overall passed in your 12th board examination except maths.

If it the condition then my answer is

Yes, you are eligible for Neet examination

Because according to the

NEET eligibility marks in class 12 to be considered are aggregate marks only for PCB subjects

• UR - 50%,

• OBC/SC/ST - 40%,

• PWD - 45%

NOTE  I am considering that you have failed in maths exam only

Hope it helps

Thank you
