The one thing that made me choose MBAGuru for my CAT preparation was their adaptive module and batch size. The kind of personal attention that you get in a small batch inspires you to study. The teacher knows about your strengths and they guide you accordingly. You can easily resolve your doubts. If you are not comfortable in any topic and you wish to study from basic level, you can attend there module classes. AIRCATs are also very useful and they helped me to stay focused in my CAT exam.
