See, I will be deadass honest with you and I promise, give it a read, you ought to learn something from it.
If you are a NEET aspirant, ok let me rephrase, if you are a serious NEET/JEE aspirant, Boards don’t matter much. Nevertheless, you will score good in boards.
So as for credentials, I got 93.8% in CBSE 2020 with PCB but the major thing is I never prepared for boards. I didn’t go to any coaching nor to any school in 12th. Just dedicated myself to learn the Subject. NEET, JEE, Boards, etc followed along.
