Hello Aspirant,

It's difficult to tell you the exact about the qualifying cutoff & admission cutoff. This score seems enough to qualify the exam as OBC category but chances seems less to get NITs, IIITs & GFTIs Etc. You can go for state level counselling. I would also suggest you to appear for JEE Main 2020 April Session again.

You may calculate your expected rank by this formula

100 - your total percentile score is the percentage  of people ahead of you. 874469 are the number of candidates appeared for Jan exam. So rank formula is (100 - your total score) X 869010 /100. If the number of candidates for April exam increased to 1200000 then your final rank shall be (100 - your total score) X 1200000/100

Using the formula

(100 - your total score) X 869010 /100

Your probable rank will be 201,610

You can also check your other admission possibilities in state level counselling to go through with the given below link.

Good Luck!
