JEE

Not possible. Sir JJ College required JEE Main percentile above 98 for B.Arch admission. So your chances are very less.

Please write about the home state for better response. However based on the JEE Main percentile you obtained, the following are the options.
1. Dr. D. Y. Patil Institute Of Technology, Pune
2. Amity University Noida
3. G. H. Raisoni College of Engineering, Nagpur
4. Jiwaji University, Gwalior
5. Barkatullah University Institute of Technology, Bhopal
6. I. K Gujral Punjab Technical University (PTU), Jalandhar.

The Joint Entrance Exam (Mains) in January 2021 could be delayed if the Covid-19 situation across the country worsens. Officials in the National Testing Agency NTA said they want to keep up with the schedule and hold the exams in time, but are not certain if that will be the case. No official notification has been released so far on the date of the JEE Mains exam, and students have expressed apprehension about whether it will be postponed or cancelled. However, sources in the NTA and the Ministry of Education told that though the exam will not be cancelled, it could be delayed because of the pandemic.
