You can check your rank  by providing your details on careers360 JEE main rank predictor but 

JEE mains rank predictor does not gives your exact rank. it just gives you an rough idea about your rank on the basis of information provided by you it is just a tool by which student can get a vague idea in their mind about which colleges they might get and can therefore apply for them if they are satisfied.

You can check your JEE mains rank at https://engineering.careers360.com/jee-main-rank-predictor
