Online GMAT Course

We chose to use screen capture videos and not live videos. Screen capture videos bring the content to the forefront. It has two other advantages - 1) Video size is small. So, if you have an internet connection that lets you watch stuff on youtube you will be able to watch the course without any issues. 2) We can write equations and use a digital pen to highlight key ideas without worrying about camera focus.

Try it free before signing up. A couple of modules of Descriptive Statistics, a key topic in the GMAT from which 2 to 3 questions appear in the test, can be tried without any obligation by signing up free. All classes have been designed and delivered by Mr.K S Baskar. He has been a GMAT tutor since 2000 and has scored Q-51 in the GMAT.
