Hello Buddy! Hope you're doing good.

After you get a seat through NEET PG and has started college then after a month or more if you get a seat in AIIMS then can leave the previous college which you take through NEET PG. Some amount will deduct from your fees and you will get a return of the remaining amount on your bank account. How much amount will be deducted totally depends upon the college, there terms and conditions. Hope this will help you.

ALL THE BEST! WORK HARD !!
