Hi aspirant...!

Hope you're doing great...!

So, with regard of you're query. Under the  marks vs rank analysis of the marks that you mentioned above  JEE mains in 2021 and 2020, are about 92-94th percentiles. the general category rank will be around 40-60 thousand.  Your SC rank depends on no. of SC candidates appeared this year in JEE mains but after analyzing previous year cutoff your SC category  rank should be 1800 - 2000.

Hope this will helps you...!

GOOD LUCK..!
