Hello

Before 2020 to get admission in one of the AIIMS you need to give the aiims entrance exam and for AIIMS Bhopal you need to have a rank within the top 200 (for general category student). For more details you may check https://www.careers360.com/university/all-india-institute-of-medical-sciences-bhopal/admission

Since this is the first time admission to aiims will be given through NEET it is highly uncertain how the cutoff will be however I would recomend you to use https://medicine.careers360.com/neet-college-predictor to see which colleges you might get.
