Hi Rajib

The academics requirements for 12th std students to appear for NEET 2023 are:

- The applicant must have completed class 12 or its equivalent, with core courses in physics, chemistry, biology/biotechnology, and English from a recognized board.

- Qualifying marks- UR- 50%, OBC/SC/ST-40%, PWD-45% (PCB)

- Gap year between 11th and 12th is permitted.

Therefore, if you retake your 12th exam in 2023 and then give NEET, there will not be any problem in the procedure. You have to retake your 12th boards since your score is below 50%. otherwise, there is no weightage given to 12th marks in NEET.

All the best for that, hope this was of some help.
