They are great at advertising. but when it comes to after sale-service, they are the least helpful. i could view the classes for about 3-4 hours and it suddenly became extremely slow and in some other systems it would not even run. i called the helpline (mentioned in the ad) continuously for 2 weeks but they would never respomd back to my complaint. i am still waiting for a respomse from them.
i am feeling sad now for 2 things - one i paid a huge amount for this, two, i am losing precious time in waiting for it to be viewed and no help from CCI.
the classes are very good, Mr. Muralidharan focusses on the concept and makes it very clear. but i am not sure if you should risk your time and money by buying the course, as the service is terrible.
