Hi Drishti

If you want to pursue MBBS ,BDS, BHMS and BAMS then NEET is the only gateway for the admission in government , private , central and deemed universities. Earlier JIPMER and AIIMS have their seperate entrance examinations but from 2020 these all are merged. Therefore , for admission in any medical institute you need to give neeet ug. For further information you can refer to this link below :

Biology also have many other scopes like BPT , Bsc in botany, zoology, microbiology ,etc their admission procedure varies from university to university. In some , admission is entrance based and some it is merit based,. You can check their official website for the procedure. Mostly registration starts in month of march.

Hope it helps :)
