Hi, notes and study material provided by Career Launcher is surely better than MBA guru. Even the mock series in career launcher is designed in such a way that a candidate is able to prepare automatically for extreme tough competition as well. Career Launcher is good at Quality of Faculty, Results, Quality of Mocks, Online tests and support. These are the one every MBA aspirant looks for the best Coaching. Hope this is helpful to you to chase your goal. I believe you got your answer about the best Coaching for MBA.

Good Luck:)

Before taking admission in any of these three, keep few things in mind. They are:
Quality of Faculty , All India Results and ranks in CAT and Quality of the Mocks, Online tests and support.
However, CL is way better than MBAGuru & Time. 
                  Thank you.
