Hey aspirant,

IIM INDORE is first IIMs to introduce 5 years IPM ( Integrated Programme of Management) course. 

IPM plus is a 9 month preparation course designed for higher secondary students both passed and appearing.

IPM express is a short term course of a  duration of 2 to 3 months and it is ideal for students in final year of schooling and who wish to prepare for exam after 12th. 

Career launcher is a Institute which is most commonly known for CAT and Management  programme. Although career launcher is a great Institute but the Institute has different branches in different cities and the facility and faculty might vary according to me.

It provides study material, regular classes with qualified faculty, etc.

In the words of Utsav Thapliyal, an IIM Indore student says, " The PDP training at Career Launcher under Mr. Manuj Mittal is truly the best and I was able to ace the interview process to get into my dream college."

There's another Institute, Smartprep, in Delhi that provides online study material and free career counseling. It also provides concession in fee and the fascinating thing is that every year student get selected in IIM from this coaching.

     So according to me, you could choose between these two as per your convenience, because these two are situated in entirely different locations. 

      Also this course is quite difficult to be completed within a month. It's a complete 3 months (IPM express) and demands dedication and practice.

You need to smartly prepare and structure your study material, constantly testing yourself through mock test paper series, stay updated with news and general knowledge, strong vocabulary, qualitative and quantitative data practices, etc.

There are many people who have qualified and joined IIM, Indore, and it doesn't entirely depend upon the Institute you opt for but partly on your dedication and passion towards it. You have to make your decision wisely here.

Hope this answer helps, in case of any doubt, please do revert back.

All the very best !!
