Dear Sneha, The criteria for selecting an institute should be quality of the following :

1. Faculty

2. Batch size

3. Study material

4. Test Series

5. Program fee

Combination of all the above factors should help you in deciding which institute to join.

As per the reviews of the students and my own experience, TIME just edges ahead in study material and test series.

Quality of the faculty is more or less the same in both.

However, MBAGuru is way ahead in the batch size factor.

Personally, batch size factor would be very important in my decision. As a student, it is essential that you get personal attention. This motivates the student to be consistent. None of the other factors are that important.

You get decent faculty in almost all the institutes, test series are comparable and study materials are easily available.

So, make your decision accordingly. 

My personal advice would be not to choose MBA GURU. I have come across many students who had bad reviews  about MBA GURU. 

All the best 

Hope this helps
