I have got 282 marks in neet 2019, i belong to sc category from rajasthan. Is there my hope for getting medical seat?

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.
This Year The No. IF student which have Score above 480 marks are more then of last year. So getting seat is More difficult this year.

There are only 60k seats in India. In which 15% seats are under AIQ Qouta.
FOR getting seat in AIQ is Very Difficult if you are from state which have low no. Of College
You can Try for Paid management Seat in top Deemed Universities.
Futher, if you need any assistance you can contact me Personally. 8446739069

Dear aspirant,  your score is certainly low and we can't expect if you will get a  seat in government medical College. as per last year's records a SC candidate must have to score at least 400 and above to get admission.
You may look forward to get admission in private college there you may get a seat.
Best regards,
Thank you.
