Hello Aspirant,

The calculation of the category rank would be difficult based on your percentile. You may calculate your general 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 general rank will be 46,926.

Based on this percentile you can have the chance to get National Institute of Technology Tiruchirappalli- B.tech EEE, Mechanical, Chemical, Civil, National Institute of Technology Karnataka Surathkal-ECE, EEE, Motilal Nehru National Institute of Technology Allahabad Prayagraj- B.tech IT, ECE Etc.
