JEE

With a rank of 264982 in the general category, options for admission to engineering colleges may not be very high, but they are still there. Here are some colleges that you may consider:
Private Engineering Colleges: Many private institutions have lesser cutoff ranks and may accommodate students with higher ranks. For example:
Shivaji University, Kolhapur
MIT College of Engineering, Pune
Bharati Vidyapeeth Deemed University, Pune
Some of the State Engineering Colleges do have openings for students of higher rank particularly for less popular streams.
Government Funded Technical Institutions: While a highly competitive list, some of the GFTIs may have a few seats opening up for the students who have a rank higher for that particular engineering stream. Counselling is a must and each college cutoff may vary in its requirement of rank in the entrance exams.

To be qualified for JEE Advanced, one must fulfill certain specified criteria like clearing the JEE Main exam with ranking among the top 2,50,000 candidates. If you got 86.35 percent in the JEE Mains B.Arch exam, you need to check if your rank comes in that bracket. In addition to that, candidates must also clear their Class 12 examination with Physics, Chemistry, and Mathematics as compulsory subjects.
Since you are interested in B.Arch, then you must also satisfy any additional eligibility criteria related to the drawing test. If your rank fits within the top 2.5 Lacs and you otherwise qualify, then you should be eligible to appear in JEE Advanced.
