Best Course for SC and CR

I am a non native student. I am having a experience of 9 years so 9 years break from books and study. I tried to study from various book in an asynchronous manner. I gave my first mock and disastrous to score V21. I score very bad . I again started hard from various books and the result was same. I did not score properly. Then I thought of buying a course and best I could figure out for non natives was e-gmat and it turns really a good decision. I have not taken a gmat yet but my score has been improved in mock gmat stupendously. Best thing about egmat is that it is visual course , so no more books. We can track the progress online though gradual short exams. Also once you finish the concept, you cannot move over to next one. I really find this course very useful who want to improve on SC and CR.
