靠天靠地不如靠自己！

Don't go to XDF if you want to hit 700. XDF is an unstoppable money-making machine that can only take you to 600, which means if you are able to score 400 on quantitative part, then you'll only get 200 out of 400 on verbal. As XDF won't teach you quantitative, its verbal tutorial is by no means acceptable. The only key to high score on GMAT is your unswervingly efforts!

Anyway, I've warned you not to trust XDF. While some materials published by XDF might be useful, the essentially dreadful courses are a complete waste of time and money. Words of advice: To vanquish SC and CR, resort to Manhattan. To conquer RC, read the Economist, Nature, Science, etc. on a DAILY basis, and there are NO shortcuts. Keep in mind that before you take the test you should be capable of reading articles from the Economist at the speed of AT LEAST 300 words per minute; otherwise you won't be able to successfully complete the verbal section within the time constraint. So do not register for the test until you're fully prepared.
