Good luck and keep asking

Hello,

Please do mention which state entrance you have taken.

If it is JEE MAIN, 

Then undoubtedly all the IIT's and NIT's are excellent for any core engineering fields.

If it for any engineering college of particular state ,then go for all the top 20 colleges of the State best colleges List.

Thanks,Hope you find this useful.

All the best! :)
