It focuses primarily on the concepts and has enough practice questions to make the concepts stronger. I'd recommend this for anyone who is starting with the GMAT prep. People at advance stages of prep can also use this to review and revise their concepts
This course helped me the achieve a verbal score of 38 on my first attempt at the exam..
I'd even recommend to view all the lessons at least twice in order to brush up the concepts. The practice questions are also very good and unlike any other prep program. The explanations that are provided are very detailed and easy to understand.
To put it in a nutshell, this is an excellent course for any GMAT aspirant
