Note – This is my personal observation and opinion.

The difficulty level of the paper before the 2017 paper was between BITSAT and JEE Main, with some questions that can be classified into the hard category. The number of reasoning and mathematics questions were almost equal.

In 2017, the format of the paper was changed considerably, with more question in the Mathematics section, and the difficulty level between JEE Main and JEE Advanced, with more questions that can be classified into the hard category. More emphasis was given to Mathematics this time.

So you can expect the paper to be challenging this year, with increased competition, popularity and awareness of Cluster Innovation Centre.
