B.Tech Computer Science and Engineering

Hello Pratap,
You need to write MPPET exam for engineering colleges in Madhya Pradesh.

I think the best CSE colleges other than IIT are:

Private colleges like VIT, SRM, Amity University and Manipal should not be considered.
For colleges under JEE Mains, you can consider this answer:

Hello Payal,
Both are same. There is no difference between them so don't worry about this topic just think about college which is better and go for it.

Give JEE Mains, score good marks and try to get admission in a good private college or your state govt. engineering college as they need only 60% in class 12th.
You cannot get admission in NITs as your percentage is less than 75%.

Norway, Germany, Netherlands, Australia and Canada are good low budget options but I would advise you to pursue Bachelor's in India and MS abroad.

Hi,
Admission in 2nd year B.Tech after completing B.Sc is not allowed anywhere in India. So I don't think you can do so but you can pursue MCA from DTU by cracking the entrance. It has almost same value.

Hi,
Some of the best colleges in India for B.Tech CSE are:
BITS, Pilani
IIIT Hyderabad
UTM, Shillong
DAIICT, Gandhinagar
The LNMIIT, Jaipur
