I found the crack isb coaching extremely helpful in getting my target GMAT score. The faculty is great and provide solid fundamentals in all sections. They are always available for doubts clarification and I was able to schedule one on one appointments with them to understand my weaknesses and strengths. The staff has been really prompt and helpful in scheduling and confirming the appointments. Overall, I would recommend CrackISB to anyone wishing to get a great GMAT score and B school applications assisitance.
