Hey,
It depends on what’s your weaker area. I’m not much aware about crackverbal.
Gmatwhiz has mixed reviews (check gmat club, I had asked a review for
gmatwhiz and got some replies). The general overview was that
gmatwhiz had too many small videos and their questions weren’t like actual gmat questions.
In my opinion, TTP is pretty good for quant. It’s a long course but is very solid and covers everything you could possibly need in quant. Whichever, online course you choose be sure to check out their trial version first. This way you can see if it suits you or not.
Other than that, if you don’t mind textbooks over online videos, then go for the
manhattan prep guides or the veritas prep guides. You can find them both online through little researching. You can also download the veritas app from play store for free and get access to all their videos from their on demand course.
For verbal, the Manhattan guides are the best. You could also look at powerscore bibles, mainly popular for CR and secondly SC. Veritas is also good for verbal, as it goes into application, strategies, thinking like the testmaker and how to approach questions. It’s pretty great but not as thorough on basics as the manhattan guides.
