Hi,
Since you have not mentioned which subject you are interested in for your higher studies, I will mention few of the top public/government colleges in Kolkata.
1) Presidency University
2) Acharya Prafulla Chandra college
3) Asutosh College
4) Maulana Azad college
5) Vidyasagar College
6) Government college of Art & Craft
There are many other reputed colleges in Kolkata but with the limited amount of information that you have provided, I could help you with only this much.
Hope this helps.
