what is the detailed plan for cracking jb ims college

JBIMS shall accept CAT as well as CET for MMS students. For International students GMAT is acceptable as well. However, cutoff is skyrocketed at around 99.7 percentile in all exams. To achieve 99+percentile and aim dor JBIMS, you should be giving lot of mock exams. CAT is not about solvibg quantitatively but about qualitatively. When you give mock, make sure you do indepth root analysis of mistakes you make and check whether the approach you make is coreect, whether there is another approach which saves time. Make sure you jot down all such mistakes to not repeat them again. You need to check which is area of weakness and why are you scoring negative. Check how much time you devote on average. Then focus on those areas more, try to solve multiple problems on your weak areas through different books like Arun Sharma, Nishit Sinha, TIME Coaching material. Check whether the solutions set has different approach and does it save your time as well, in the exam hall you have to shortlist questions you're comfortable and confident with to save time and achieve accuracy.Give more mocks on it and eventually you'll optimize mistakes and achieve better accuracy ratio.

For JBIMS to create a detailed plan, you will have to customize as per your routine and daily tasks.
The time period required if you are preparing for the first time could vary from person to person. Lesser time may be required if you have prepared for CAT / XAT as you have already gone through most topics.

Attempt previous year sample papers and even given online and offline mocks. Give sectional and full length mocks.
After the mocks, the main task is to analyse them and understand where you went wrong and areas where you can do better.

Time Management is important. This is the most important tip. Time yourself in practice. Become a machine. Sum up the calculation in a limited time frame and do not ponder on one for long.

You need to score a good percentile to get into JBIMS. Aim above 99.8 percentile to crack the admission. So prepare accordingly.

Good luck.
