MBA Entrance Exam

Hi,
There are many of them such as T.I.M.E, IMS, CL, Tathagat, CMS and some small local names as well.
But you should only go for this option when you are ready to study well, and you are one of those who can not study just by mere sitting at home.
At the offline coaching centers, you can choose from the weekdays or weekends classes as per your schedule. The main thing that you will have to take care of, is that you do not miss any of the classes, and you remain focused by studying apart from coaching classes as well.
Online Coaching.
If you go for this, then you have the option to choose from all over India's the best coaching classes. There are many like Hand ka Funda, iQuanta, etc. In fact, you will find almost all of the offline coaching classes providing their online courses as well.

See, CAT is an entrance which is all about your aptitude in 3 fields basically and that is verbal, logical reasoning, data interpretation and quantitative aptitude. So, it's not about going with many books and hindering around to learn from different books as of my experience I found that NCERTs are the best to revise up all your basic concepts upto 10th standard. Moreover, for English and other sections, I suggest you to go through all the books you get from your coaching classes or buy some coaching institute module which is freely available. And practice from that as much as you can. And, if still, you want more and your soul is not getting fulfilled then you can choose to go with arun sharma it is one of the best or can say the best book to practice for CAT and if you do it properly, you will be able to crack CAT because the difficulty level they set the CAT do not go beyond it. So, all the best. Do practice and give test as much as you can.
