I do not have much idea about it. Yes, it is difficult. There are 29 seats in the general category and plenty of applicants. There are usually just two counseling sessions, because not many people cancel. So, it's not necessarily the standard of questions which makes it difficult-it's the competition, thus making the test a high scoring one. If your board percentage is exceptionally good, there's a chance that you might make it through with a mediocre admission test score, but otherwise, it becomes pretty difficult. Not preparing for JEE is irrelevant. A higher level of preparation obviously helps, but there are a lot of people who get in from commerce and humanities backgrounds. The questions are not as difficult as the JEE level, they are very conceptual and application-based and can be tackled by a thorough reading of your +2 textbooks.
I followed RD Sharma and SN Dey's books through the 2 years and revised them again before my admission exam. Try to do the MCQs at the end of the chapters. Apart from these, solve previous year's papers-they are available on the college website. When I gave it last year, the exam had a lot of calculus and it's applications and more of a business math approach. There is also a 20 mark essay after the Maths section, so make sure you have enough time left over for that.
Best of luck.
