Im studying 12th,I wanna get into universities that provide research fields(like IIsc) name other such universities and the exams to take up
Well IISERs are the others. There are 7 of them so you could check their admission process here. https://engineering.careers360.com/articles/iiser-admissions
See most universities provide research but say from the post graduate level onwards. So that is another way to go into research.
