Running out of Practice Material, test May 5th

I've been through all the Manhattan Gmat Quant topic books, and the OG quant review. I've done some verbal, but not much, as I don't have many problems with my scoring there.

This is also my second time taking the test, last time was Jan 29th, I scored a 680 : 42 V, 39 Q.

My last GMAT Prep CAT was a 750 : 44Q, 49V. I'd be very happy with this score, but would be surprised to be able to recreate the Verbal score.

So far the GMAT club tests are kicking my ass. I'm getting about 50-75% right, I find them to be exceptionally difficult, and the last two have been very discouraging. I'm scheduled to take the 7th one tomorrow.

I am debating stopping with the gmat club tests because they are so hard and the questions answer explanations are so poorly written that they don't make much sense. I don't get much out of them except frustration.


My biggest weaknesses are...
Algebraic translations, Rates, and exponents, combinations, and probability. I'm not spending a lot of time on combos and prob because I have the basics down, its just when you combine the two that I get thrown off. I need to brush up on the fundamentals of algebraic manipulation and rates though.

I might try the last 40 quant questions in the OG tomorrow. I haven't touched the original OG since the first time I took the GMAT in January, but I think the OG questions are the best quality and may be worth doing again.

Does it make sense to just take CATs over and over again at this point? 2 weeks doesnt feel like a lot of time, and I dont want to waste it!
