Uttar Pradesh

It's quite tough to compare to notch colleges. But let me try. Placements in DTU are far better than HBTU. HBTU lacks in proper infrastructure. DTU situated in Delhi has its own way of advantage. DTU has a good reputation. So, I could conclude by telling DTU would be better. This is my view of thinking.
Hope this could help you.

IET Lucknow is much better college than upes Dehradun. Here, you will find best infrastructure, placements as well as academics. IET Lucknow comes under top 100 reputed government colleges if India.

No, you can't get admission on the basis of UPSEE scorecard. You have to take admission on the basis of JEE Mains scorecard. HBTU is no longer apart of UPTU since 2017.

HBTI-Kanpur is no longer a part of UPTU since 2017. Now, it has become a university. If you want to get admission in HBTU, you need to clear JEE Mains with a descent rank to get admission in descent branch.

Hi, NIOS certificates are legally valid in all institutes and universities in India. As it is a board under central government like CBSE and CISCE etc. Further the minimum eligibility criteria for BHM from Amity University, Lucknow is 12th passed only. Hence you are eligible.

No, you are not eligible for BTC, because for BTC you have required 50% in graduation. If you want to become teacher, you can do PPT at class 12th level.

You can do but if you can try and the college give a permission, you can do it.

MS Ramaiah is better, here you can get exposure yourself to the more opportunities to the business world and in terms of placements every year from MS Ramaih most of the students got placed in various industries.

You can get this college at this rank only in the spot round of the counselling. Before that, you won't get admission in this college as your rank is too high for that.

There are only few chances for getting this college in CSE branch. But, you can go for few more rounds in counseling. Try hard and hope for the best.
