You must be feeling this way because of societal pressure. But KMC Manipal is an amazing college, and you’ll really like it here.
Some of my classmates left their AIIMS seats (not AIIMS Delhi though) to study at KMC Manipal. I agree that in comparison to government colleges, the fee at KMC Manipal is quite high (if you don’t get a scholarship). However, you’ll get all the top facilities in exchange for that. I know of successful medicos who graduated from this place.
AIIMS Delhi and KMC increase your chances of qualifying USMLE drastically. KMC Manipal has a favorable reputation in foreign universities. The faculty over here is quite good. The library, sports, and other facilities are all top-notch. Another good thing is the complete absence of reservations.
So you shouldn’t be disheartened because of all that you couldn’t get. Instead, make the most out of the opportunities available to you.
