Hi,

There are some entrance test you have to crack- JEE Mains, JEE Advanced, MHT-CET. While some universities have their own entrance exams. So, it depends on the institute/college you want to take admission in. JEE is a national level exam while MHT-CET is a state level exam. For top colleges like IITs, you have to crack JEE Advanced. The admission process is tough in those institutes. You also have to crack GD and PI round after that. Some colleges accepts JEE Mains score. Plus, you should be eligible for the exams also.

All the best!!
