I got 207 marks in neet and I hav nt registered for it so I want to do mbbs or bds can I get a seat and what will be the fee per annum

AS I see your marks in NEET UG 2018 you have very less chances of get Seat in Deemed Or Private Universities Colleges.
Cutoff for this year for getting any private or deemed Colleges you have to score around 450 under AIQ & 430 under state qouta for Open Category.
You have even less chances to get any seat if you belong to any category under your state.
You can Try for Paid management Seat in top Deemed Universities.
Futher, if you need any assistance you can contact me Personally. 8446739069

Based on this score the chances are less to get a seat in Government colleges but you can try for the private colleges & deemed universities. The fees structure varies college to college.

Good Luck!
