Hello there,

Jain University entrance exam is really easy, not as hard as IIT entrance exam. With basic knowledge you can easily clear it. There are generally aptitude tests to test your grasp on English language, maths and general knowledge. They test you for your application skills. You must have strong concept, brush your mathematics concepts, read a lot of current affairs and static general knowledge. Do don't have to buy any book just be confident.

Good Luck!!
