Engineering Entrance Exam

If you scored around 5 lakh in JEE Mains, admission at Ajay Kumar Garg Engineering college (Ghaziabad) is almost impossible even for civil or mechanical branch since their closing ranks go way beyond.

With 315932 crl and 11632 obc rank from up you probably won't get into top NITs or IIITs but you can try for lower branches in newer NITs like Mizoram, Sikkim, or puducherry. You can check GFTIs and state colleges in UP like IET Lucknow through UPSEE counselling.

You can not  get any college with 15 percentile in JEE Mains in Pune. You should try getting colleges which are based on your 12th score or you can get direct admission. You will not get any college with 15 percentile in JEE mains.

With 8620 ST category rank, you can not get most of the NITs but you have greater chances to get GFTIs and IITDM. You can also try for state engineering colleges. You can also try in various universities.

No, you can not get into CSE/IT/ENTC in NIT/IIIT or GIFT with a CRL of 273071 and an OBC rank of 95501 in JEE Mains. You can check for other private colleges and state engineering colleges with other means.                             

With 66.1357 percentile and an AIR of 505570 in the general category, getting admission into any IIIT (Indian Institute of Information Technology) through JoSAA Counselling is highly unlikely. Here's a detailed explanation

IIITs have very high cutoffs, especially for General category students. Typically, General category closing ranks for IIITs go up to 40,000–70,000 AIR (approx), depending on:

The branch (CSE being most competitive)

The IIIT's location and popularity

Your rank (505570) is far beyond these cutoffs.

With a JEE Main rank between 8 to 9 lakh, your chances for NITs, IIITs, and GFTIs through JoSAA/CSAB are extremely low, even with reserved categories. However, you can still get into decent private and state engineering colleges—especially if you make use of state counselling, private university entrance routes, and some lower-tier institutions.

It will require a very high JEE Advanced rank to get admissions in an IIT. In the top IITs (e.g Bombay, Delhi) popular branches such as Computer Science Engineering (CSE) may require an All India Rank (AIR) of below 100-200 in the General category. In other faculty members and newer IITs ranks can go up to 10,000 or more depending upon the institute, course or degree. These cut offs vary every year depending on the difficulty level of the exam, applicants and seats.
