Wanted to prepare for DILR section , honest reviews for cracku, and whch course to choose

Go for Complete Cracku. A five month batch is starting from tomorrow. It has excellent videos, good mocks and sectionals (with video solutions) and complete access to Study Room and Daily Target. In my opinion, it is the best online course to prepare for CAT and is very comprehensive. You can enroll to it here: 5 Month CAT Batch
