Hello Aspirant,

Yes with 280 marks in NEET 2020 you could get admission in private colleges, But my advice to you is not to opt for private colleges as if your really concerned about your career you think about reappearing for NEET 2021 and scoring 500+ marks and cracking an seat in any reputed government college. As private colleges would charge you high fees and then you won't be getting good placements compared to government colleges.

Hope this helps

Thank you
