Colleges in Pune

Hello Shruti,
I am afraid, COEP does not have this facility. But you indeed can seek lateral admission in COEP by following procedure laid down by DTE, Maharashtra on their website.
Best wishes.

Maybe because some private colleges offer admission to 10th pass out candidates but for Diploma course. But you can go for degree programmes after completing your 12th. You need to take NCHMCT JEE exam and get a good rank.

The average salary of an AME certificate holder is INR 20000-30000 per month (in the beginning).

I would advice you to visit the website link of BVIEER from here:
