Can you suggest to me some colleges for B.Tech in the north and south sides of India?

In the north region, you can go with Chandigarh university or lpu and if you are searching for a full government college then you can go through Punjab technical university.

Hello Aaditya, I am attaching a link that will give you all the required information. https://www.shiksha.com/engineering/ranking/top-engineering-colleges-in-india/44-2-0-0-0 Best wishes to you.
