Hello Aspirant,

Yes, you are eligible for NEET and Veterinary courses if you fulfill the required PCB (Physics, Chemistry, Biology) percentage criteria even if you failed in Mathematics.

Eligibility for NEET:

You must have passed in Physics, Chemistry, Biology/Biotechnology, and English individually.

Minimum required marks (General Category): 50% aggregate in PCB

For OBC/SC/ST: 40% aggregate in PCB

Mathematics is not mandatory for NEET eligibility.
Since you passed Physics, Chemistry, Biology, you can appear for NEET if your PCB aggregate is above the required percentage.

For Veterinary ,eligibility is same as NEET eligibility.

All the best for your journey.
