Dear Aspirant,

In the application of NEET there is no need of 11th class marks. They take your  12th marks and 10th marks only. Yes you can give  the biology marks but they may consider because in the eligibility criteria it is clearly mentioned  that a student must PCB as the 12th class subject. So they may consider.

Hope this helps.

Good Luck!
