There are certain colleges out there whose admission procedure is quite direct i.e just on the basis of 12th marks also called merit based selection.

Few colleges in Andhra Pradesh and Telangana conducts their own Entrance exam like APEAMCET or TSEMCET.

Most of the colleges enroll students through NEET.

So, i would suggest you to please focus more on NEET rather than any state level Entrance exam.

All the best!!
