Hey aspirant!

Firstly, understand that it is the percentile that is reflected in your NTA score of Jee Mains Paper 1 results and not your percentage. Now, It is difficult to predict the exact ranks currently as the April session has yet to take place. However, you can predict your expected rank by this formula:-

(100 - your total score) X 869010 /100.

If the number of candidates for April exam get increased to some number, say,1200000 then your final rank shall be (100 - your total score) X 1200000/100

In your case the expected rank comes out to be around 121661.

Also, you can use this college predictor to know what colleges you would get based on these January scores
