Hello

MHT- CET is a common entrance test conducted by government of Maharashtra.

Eligibility candidate have to complete or appear in 12th from science stream

Now let's come to your query science stream have main 4 subjects i.e physics, chemistry,Maths, biology some students drop maths and some students drop biology and some students take all 4 subject. It totally depends on student interest.

So if you have all 4 subject in your study so this time you can select pcb for CET entrance test. But if you have all only 3 subject like PCM so you are not able to select bio and able to give entrance in PCB.

I HOPE THIS HELPS YOU
