Hello Shivansh. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

I had answered a previous question of years wherein you mentioned that you had got only about 85 marks in the exam. 

I am afraid that this is well short of the expected cutoffs for qualifying JEE Mains this year according to this site:

Nevertheless, I would like to direct your attention to this link for more information about some preparation tips for JEE Advanced:
