After attending our GMAT Plus class and getting the related knowledge and strategies to solve problems, how to review the GMAT by yourself to get 750 or more?
Here, we recommend Method of Concentration:

As shown from the chart, during the first 30 minutes, your efficiency for learning a certain subject, say SC, is relatively low, simply because you need to firstly review the knowledge you learnt and it normally takes a bit of time to get concentrated. Therefore, if you want to learn multiple subjects simultaneously in one day, most of your time will be wasted in reviewing different subjects when you switching between them. Thus, we suggest that you study ONLY ONE subject for a period of time, say 1 to 2 weeks, until you really conquer that subject!
