Extremely helpful!!

When i gave GMAT the first time i was scoring around 740 in the mocks and was sure to get a good score. But when i received a mere 640, It was a huge shock to me. I came home & immediately signed up for this course. My quant was ok.. but fared very badly in English. To tell the truth... i hardly understood SC. I mugged up the rules and applied them wherever i could. But this course made me see SC in a new light. I could understand sentences in a way never before, without even trying, i could easily make out the verb, the subject, the modifier, the clause..... it never felt so easy... i haven't given GMAT again yet... but i already feel so confident...
