Dear Aspirant,

If you fail in mathematics in your plus two then you have to give the re exam again. For the Chemistry HONS most common eligibility requirement is 60% marks in the plus two or equivalent with PCB or PCM streams,

Hope this helps. Thank you.

Hello student I request you to please help me with your query a little more so that I can check and provide you the exact eligibility criteria.

If you've failed in mathematics subject you can appear in improvement examination.

Feel free to comment if you have any doubt

Good luck
