Engineering Entrance Exam

No, this college's intake is only through merit basis over JEE & SAT. This college has brightest minds of India, so you need to qualify JEE Mains. Else, you need to score above 2000/2400 in SAT. As you said I think, you did not qualify for JEE Mains, then you are not eligible to get admission in this college through management quota.

Hello, hope you are doing well. You need to search for the JEE Main paper 2 score accepted college list after that, check for the dates and criteria for the particular college state wise. If you are searching for home state. It is okay, but if you are searching for other states, then you need to find the eligibility criteria for that state also. And then, go for counselling.

With this rank, you can go for your state government engineering colleges only, as you have scored very less marks.

You can go for your state government engineering colleges, as you have scored less marks. Or, you can also go for private colleges.

You should opt for FIITJEE-Meerut, as it is one of best IIT coaching center in Meerut.

I guess, AAT is only for pursuing architecture from the IIT's
For NITs, only your JEE marks are enough.
Is this the Architecture Aptitude Test you are talking about?

Hello,
Hope you are doing well. Congratulations on passing the JEE Advanced examination with its cutoff range but as you said you have only 64 % in the 12th board so you are not allowed to get the college through JEE Advanced because it requires 75% to be eligible for IITs. You should go with JEE main score under sc category and try for NITs if you have a good ranking.

You cannot get any NIT or IIIT but you can get some private colleges through the Jossa or you should try with the state counselling for private colleges. You can also go for IPU, Nirma, Amity, Chandigarh University, JECRC, etc.
