Colleges in Ahmedabad

It depends on the place where you are living.
If you are a resident of Ahmedabad, choose Nirma.

IT department of Nirma University is better according to the way they teach.
Nirma University has well equipped network facilities and all the system is updated.
The faculties are also qualified.
Sarcastically, the IT department do not have a good football team.

Placement record for computer science is very good in Nirma University and it is said that every year 100% placement is done.
Also, the package of recruiting companies is satisfactory for the students.

Your B.Tech might prove as a downer for IIM A/B. I would suggest you to try upwards of 99.7% marks for calls from top B-schools in India.

With your engineering score, it is not possible to get admission to IIM Ahmedabad. I would suggest you to try colleges like FMS or MDI

Dear Mansi, NIRMA gives preference to UGAT if you are graduate as under graduate. But if you are graduate then I suppose you can give it a try.
