UPCAT

IET, Lucknow is far better than the UPES Dehradun as UPES is a private college and IET, Lucknow is a government college. UPES stands nowhere in the national ranking but IET does.

See, there is no such criterion for the admission in UP colleges. In private colleges, you can get admission with any marks scored by you.
For a government college, you have to score a minimum of 350 marks to get into any lower-ranked government college.

Yes, you are eligible for UPSEE if you have opted science stream in class 12.

You should have at least secured a rank under 5K to get admission in good government colleges (should at least 350 marks to be in the safer zone).

For admission in JSS, you should have atleast under 5k rank (atleast 350 marks to be in a safer zone).

Sorry, you have a very hard chance to get there. Try in other colleges like IMS or RKGIT-Ghaziabad, you can also try for direct admission.

There are many competitive exams and for cracking the same you need to study hard and smart, you can join the institution or coaching classes which are offering the coaching for the competitive exams, or you can do it by yourself.
