i am a pcm student and did not take bio throughout class 12 can i still give cuet exam? also can I still do bsc in physics at iiser?
Yes, absolutely! If you are a student of PCM, you are not required to take biology in +2 to appear in the CUET exam. If you want to do B.Sc Physics at any IISER, you are free to do so even without having Biology as one of your subjects in class XIIth.
Hope I have answered your question. All the best!
