Which engineering shouldi choose to pursue MSC in physics after graduation ( I know I won't get admission in bsc physics with my cbse marks

Your question is not clear to me.

Is it you are asking for engineering in physics since you will not get bsc physics??

If this is the question than the answer follows-

You can have dual degree in engineering physics from some IITs and NITs. You need to clear jee main for NITs and Jee advanced for IITs. But you need to have 75%+ in CBSE.

Some of the institute which offers the course are

NIT patna

SVNIT surat

IIT kanpur

IIT kharagpur

IIT madras etc..

If it was not your question that sorry! You can drop your question in comment

Hope it helps!
