All the very best and good luck.

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

Please note that the JEE Mains authorities will release the official answer keys of the JEE Mains offline and online exams a few days before they announce the results. 

Nobody can memorise all the 90 questions and tell them to a coaching institute. All of them either ask their students to recall some questions or otherwise they wait patiently till the JEE Mains officially releases them. 

Hope this helps you and all the best!
