Sir,I have score 70 percentile in jee main . Can I pass the upsee ?

Hello Aman ,
Yes you can pass the UPSEE.
UPSEE exam is simple in comparison of jee main.
The question comes in jee are concepts based while most of questions in UPSEE are formula based or some questions are also fact based.

To clear the UPSEE with good marks you should do previous year question from question bank.
It helps you to increase your marks in a limited time period also many times question concepts repeat in UPSEE exam.

If you have any questions remain than comment below.
