Hi there,

Hope you are doing fine.

There are a lot of options available  through which you can get the mock test for the jee examination and prepare for the exam and make your startegy.

You can visit the official website of the nta and then check the mock test section to give a detailed mock jee examination.

Also, you can enroll in the various coaching institutes mock test preparation and then give the required jee mock test to prepare yourself for the examination.

They are available at a minimal cost and can prepare you for the exam. Also, you can prepare by buying the previous year booklets and then practising from there.

Hope this all resolves your query.
