Hello Prerana, There are about 200 college that accepts ATMA scores all over India... AIMS conduct 5 ATMA exams each year. Out of them January and February ATMA 2018 exams are over. Next three ATMA tests are scheduled for May 27, July 1 and August 5, 2018.

I'm sending a LINK that has lists of colleges that accepts ATMA 2018 scores + their cutoff demand + Fees structure + Average placement + these colleges will accept admission as long as you clear their ATMA exam...
