Dear Student ,

As per user location , I assume you're asking about MHT CET.

Look, MHT CET is a state level Entrance exam , to get admission in the Govt and Private colleges of Maharashtra .

But if you want to pursue B.tech from any premium Institute like IITs, NITs or any GFTIs , then you must appear for JEE MAIN(for NIT, GFTIs) and JEE ADVANCED( for IITs)

You can find more details about MHT CET from here :
