Engineering Entrance Exam

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.

Hi,
Preparatory course are the courses which provide the required guidelines and guidance to crack any examination. Its given by many coaching institutes. These coaching institutes are private in nature. Most of the cases they provide their own notes and study material for the examination.

Hi,
Congratulations for clearing JEE Mains. Starting to prepare at this 11th hour for the JEE Advanced is not going to help. JEE Advanced requires thorough preparation from Day 1. There is no sufficient time left to perform outstandingly well now. However, at this time one can just go through all the past years' papers and important portions.

It's not possible to prepare for Advanced level in just 22 days. However, 22 days are just enough for the revision of topics and mocks. In order to prepare more in these 22 days, make a strategy of solving more and more of practice papers and mocks. Keep time for revision and analysis of past years papers so as to spot which area to focus more. All the best.

There are chances, of course. I suggest you to contact the university yourself and be more clear regarding the situation. Good Luck.
