Do we need to prepare CAT for the IPM course of IIM Indore?

For the IPM course of IIM Indore, there is a particular IPM paper that takes place for admission. The format of the paper has changed over the past 3 years. CAT and the IPM exam conducted by the IIM Indore are both different. The format of the IPM paper is as follows:

• 40 Questions - MCQ Type - 40 minutes (Quantitative Ability) 
• 20 Questions - Short Answer Type - 40 minutes (Quantitative Ability) 
• 40 Questions - MCQ - 40 minutes (Verbal Ability) 

Although both CAT and IPM exams are different, the format of both of them is the same. Some short answer-type questions are not MCQ type and are slightly different. Although the maths section is higher than the other section in the exam due to the short answer-type questions, the difficulty level would not be much. The cut-off for Quantitative Ability of the IPM exam is nearly 25-30%, therefore you need to go through a lot of Advanced Mathematics and should practice the CAT level mathematics well. According to the marking scheme, Each correct answer is +4 in the exam, and for the wrong answer, there is -1. This negative marking scheme is not applicable for the short answer questions.
