colleges accepting UPCAT

I am going to put some facts here.
UPSEE 2016 432 marks-Rank around 3800 in General Category
UPSEE 2015 432 marks-Rank around 1600 in General Category
UPSEE 2014 432 marks-Rank around 2300 in General Category
For getting a government College, your rank should be under 6000, if you belong to general category.

I think you should choose government UPTU colleges if you have a good rank and UPTU colleges should be IET, HBTI, CSJMU and Bundelkhand University. These colleges have very good placement records and these are top engineering colleges.

As you already known that the best college of UPTU is HBTU, but is no more part of this organization. So, for CSE, you can try IET-Lucknow, but I will say your college does not depend but your branch depend upon placement, and CSE is extremely good branch in whatever college you got.

Yes, you can get admission for B.Arch and in colleges such as:
IET, Lucknow
Faculty of Architecture
Netaji Subhash Chandra Bose

There are 20%-30% seats are reserved for the students who are taking lateral entry in every college. The seats reserved for lateral entry may differ in some colleges. The fees for the degree engineering course may differ from college to college. So, you have to go through college and know yourself better. All the best. Lateral entry students seats are depending on the college that you have preferred for yourself as each college have its own quota for Polytechnic students. Fee structure is also depend upon the college that you prefer the most.

Try for RKGIT or GL Bajaj.
