Hello Aspirant,

No, for 300 marks in NEET UG it is tad difficult or some sort of impossible stuff to get seat in any of the AIIMS even in the mop-up round because even for ST category which has lowest cut-offs among all the categories, for that category as well the lowest cut-off was around 550 marks for seat of AIIMS in 2020. Also on 300 marks any government medical colleges is quite difficult through AIQ counselling so if you got 300 marks then you have only option left as Deemed universities through AIQ counselling.

You can try for following deemed universities :-

Saveetha Medical College, Chennai:- 265 marks

Dr. DYP Edu. Soc. Deemed Uni., Kolhapur:- 262 marks

Vinayaka Missions Medical College and Hospital, Karaikal:- 257 marks

Krishna Institute of  Medical Sc., Karad:- 253 marks

JLN Medical College, Datta Meghe, Wardha:- 239 marks

Mahatma Gandhi Medical College and RI, Puducherry:- 231 marks

Chettinad Hospital and Research Institute, Kancheepuram:- 215 marks

Note that the above prediction is made on the basis of previous year's cut-off and the cut-offs are bound to change every year depending upon various factors such as the number of candidates appearing in an examination, the number of candidates qualifying an examination, difficulty level of the paper, and so on.
