Computer Science and Engineering Ranking

This college does not depend on the ranks they have their own exams, Yes you did absolutely right because as far as college is concerned on academic basis AKG and ABES are at the same level. If You want do the things by yourself then AKGEC is the worst college. If you will get selected offcampus in any software company then you will not get NOC from AKGEC, In my opinion you have done well because at this level all the software companies which will come to AKGEC also come to ABES. Administration of AKGEC is very bad, in the sense that they never support students. So do not regret you had made a good decision, college is only a platform. You have to do all the things by yourself.

Yes, you can get NITs or IIITs with your rank. All you need to do is some of these steps :
Your choices must include all the branches of NITs. You can omit some of the North Eastern NITs but you must include every branch of the central NITs. Wait till the very end of counselling. Most of the times you can get good NITs or IIITs in the 7th or Special round. Make a list of your choices and arrange it according to your preference and fill it accordingly. According to my prediction you can get a seat in a newly opened IIIT. If you are going to choose it please do check it's Mentor Institute because it can determine your campus life in the institution. Let's hope for good. All the best!
