MBA Entrance Exam

I personally went to the institutions like CL, TCC, T. I. M.E, ERUDITE and IMS to enquire about the coaching, however my first impression was that all of them provide the same facilities. So, I checked upon my seniors from college who are currently taking coaching from these institutions and here is what I found -
Here is the list of coaching institutions in Kolkata along with their pros and cons:
Career Launcher:
On enquiry CL seems like a good option that provides excellent facilities. But when I asked students who were taking coaching from CL, they recommended not to join the institute. It takes hours to grab a chance and clarify a single doubt of 15 minutes during the doubt clearing sessions. I also checked the Google reviews and it conveyed that individual attention is not delivered. Erudite:
This was the only place where I saw one to one doubt clearing session's actually taking place. When spoken to students from ERUDITE, they said that it is an amazing learning experience. The doubt clearing sessions are so efficient that it is helping them to gain more confidence on their weaker areas of the subject. The biggest advantage is that a personal mentor is attached to every student which makes the entire learning process quite smooth. TCC:
When enquired the management claimed that they provide personal attention and counseling. However their brochure says that TCC has a faculty of only two teachers and have batches of 100 students. This is the reason why I think it is practically impossible for the faculty to deliver their promises. T. I. M.E:
On enquiry, it is easily understood that the infrastructure is not so good. Also, the timings of the classes are not flexible. They only have one batch from 5pm to 7pm on weekdays (Tuesday to Friday) or on weekends from 4pm to 8pm. One to one doubt clearing sessions are not available. I. M. S:
The coaching fees are much higher than any other coaching centre of Kolkata. They do claim to provide expert faculty and personal mentoring. However, google reviews say something else. On the basis of my research for the project, I would highly recommend ERUDITE for CAT/GMAT coaching.
