Indore: The Gold Standard
Indore focuses heavily on Higher Maths (Calculus, Trigonometry). It has a Short Answer section with no options and a higher difficulty level.
Rohtak: The Speed Test
Rohtak is simpler but faster. You need to solve 120 questions in 120 minutes. It includes Reasoning, which Indore does not have.
JIPMAT: The Balanced Paper
Joint Integrated Programme in Management Admission Test (JIPMAT) for IIM Bodh Gaya and Jammu is a more 'standard' aptitude test, similar to a mini-CAT.
