Hi, we cannot calculate your marks on the basis of this information as their is negative marking for wrong answers. You can use this formula to calculate your marks-

(Number of correct answers)×4 - (number of wrong answers)×(-1).

Though your percentile cannot be calculated on the basis of your marks as your percentile have been calculated after normalisation which means a student who has scored less marks than you may have a higher percentile than yours because this paper was more difficult in comparison to yours. So you can calculate your marks but for your percentile I would suggest you to wait for the official announcement of the result. The result will be out by 30th of April.

All the best!
