As per the official website of JMI, there are no prescribed website for the entrance test. So in this scenario I would suggest you to prepare the 11 & 12 th syllabus for the entrance examination.

You can check the official website by yourself just by following the link provided below:

I hope this answer helps. All the very best for your future endeavors!
