Hello,
I would like to say you that ranking of a student depends on a lot of factors because if talking about JEE main exam a large number of students appear for this exam so in that case a lot of students gets the same marks but than to you can see the difference in ranks because there are many factors through which ranks are given to the candidates and also it can happen that there might be some error you have been facing so you should try to find your rank from some other predictor app as well. Now if you have to check for your JEE main rank than you can use the below given rank because i think it might help you with getting you a proper rank.
Thank you..
