HEY THERE!!!

1. Generally speaking, if you’re missing Chemistry in your PCM group, you can’t simply use your Biology marks as a substitute—educational boards and entrance exams typically require specific scores in Physics, Chemistry, and Mathematics.
2. They’re quite strict about this; Biology is relevant for PCB, not PCM.
3. If you’re aiming for courses that require PCM, you’ll need the actual Chemistry marks, no swaps allowed.
4. Of course, there might be some odd exception buried in a particular board’s rulebook, but that’s rare.
5. It’s always wise to double-check the official eligibility criteria, but in most cases, substituting Biology for Chemistry isn’t permitted.
