hi BB,
i have been researching on test prep course to take up after i performed miserable in gmat (600: equally bad in Verbal, Quant and IR).

i aim 700-720.
1. thus far Knewton sounds fine. However, have read a lot of negative comments about their mock tests- the scoring is weirdly low and they dont offer proper explanations to the CATs and that you can not retake if need be! Thats definitely not a good thing. Is it really so
2. Also, have read a lot about their quant section being mediocre, much easier than the real gmat. Thats again not a good news. How are their strategies though? Applying them can you aim a 50 at quant

I am from a non-math background.
3. What all is included in their online package, its bit unclear to me from the link provided. Do they send you books and other material hardcopy as well or its just available online on their website? i really prefer books to online material. hate to keep studying on the computer.
4. i can see there is a discount- $101 when you sign up- how does this work? how much do i actually end up paying from my credit card? $349 or $248? And how do you get the
gmatclub tests worth $250? how do you avail. Isnt the actual cost of these tests just $99?
5. How is gmaxonline prep- their tests, material and strategies
Thanks for your comment in advance
