Hello Aspirant ,

You are asking good question ,

From your percentile 89 in jee mains 2020 by obc along with state quota , you have a  chance , but confidently.

But you have a chance of to getting mining , petrolium,chemical engineering etc.

Other wise i suggest you to choose other exams like BITSAT, SRMJEE, VITEEE, GUJCET, MHTCET, etc .

I hope this information will help you.

THANK YOU.
