Hey,

As we all know cracking IPM indore isn't that easy. The syllabus is quite different from what you study in school especially if you do not have maths.. Make sure that you don't loose a touch with maths. Because you need to strengthen your basic maths in order to crack IPM. Also I'll suggest you  to buy Wren & Martin for Grammar and Word Power Made Easy For Vocab which will really help you boost yor verbal preparation. For passage, i should advice you to read The Hindu which would help you in developing reading skills as well as your Current Affairs Parts. Also try solving one set of DI and LR each everyday. You don't have to devote a lot of time. 3 hours of study daily will be sufficient. You can also join some coaching for the same.

Hope this helps.
