Hello Bhavya,

With a 90 percentile in JEE B.Arch and belonging to the OBC category, your chances of securing admission to SPA Vijayawada are slim, as the cutoff for OBC candidates typically ranges between 77 and 81 percentile.

However, you have a better chance of getting into some NITs, where the B.Arch cutoff for OBC-NCL candidates generally falls between 70 and 75 percentile.  Institutes like NIT Hamirpur, NIT Patna, and NIT Raipur may be within reach.

It's advisable to participate in the JoSAA counseling process and consider applying to multiple institutes to increase your chances of admission.

I would recommend you to use JEE Mains College Predictor Tool by Careers360 to get the list of possible colleges you can get with your rank or percentile.

I hope this answer helps you. If you have more queries, then feel free to share your questions with us, we will be happy to assist you.

Thank you, and I wish you all the best in your bright future.
