I have scored 53 percentile in jee mains so what should I do either give April exam also or not

Hello Aspirant

Firstly use this below formula to predict your rank:
Rank Formula = (100 - your total score) X 874469 /100.

On the basis of rank only the Colleges are decided.
Then go for college predictor I will provide the link below from careers 360:

After knowing your college with you respective categories.if you didn't get a good College.Then you have another chance to score more in jEE mains April exam.

The cutoff is taken based on both the exams.if you get 95+ percentile there will be a chance to get Nits.

If you have any questions further let me know.

Thank you!!!!
