Dear Applicant,

I hope you are doing well. I can understand its abot of tedious job to choose a college that will benefit you. This can be very confusing for sure. No worries i shall try my best to help you.

The first thing u need to look out in a good college are the following :

1. Recognization : check if the college is accredited by NAAC or  is linked to UGC, whether its autonomous or the type of course they offer. This will tell you the level at which the college is at.
2. Placements : if the college offers good placements to you than it's good. Some colleges don't have the potential to offer good placements to their students thus it becomes a drawback. If a college has good ties to highly reputed companies than it will benefit you exponentially.
3. The environment : the environment or the facilities they offer you like wife, good food, the level of the library etc.. even look out for reviews of the infrastructure.

These are some of the things u can keep into consideration. Choose the college that will provide you the best and caters to the needs of the students and not just fill their pockets with your money. After all you will be paying quite some amount of money to study.

Hope this helps u a bit!!
