I've noticed that my LSAT experience has helped me with CR and RC questions. The LSAT's logical reasoning questions are actually tougher than CR questions, at least from my perspective.

Still, you want to drill for the actual test you're taking.

By factors of 42, I take that literally: 1, 2, 3, 6, 7, 14, 21, 42. At least these factors. I (also) first ran across this type of problem in a Princeton Review book, so credit to those guys. Question, simply: If KL has the factors of 154, it must be a multiple of 154. They've given us 11. All we ne...

They say the questions are taken directly from past GMATs. At the same time, it's a CAT and so the questions are being drawn from a pretty large base. I didn't see repeat questions; I've gone through GMATPrep but haven't dug deep into the OG like some of you, so you might notice a few repeats that I...

Since it's a data sufficiency question, we only need to figure out "a" and "b." In this specific question, we don't even need to simplify that equation in the stem. (2) might strike people as "the complicated one." ab = -10 and we already know ab^2 = 50. Compare ab^2 an...

You're asking the right questions. I'd say "the big orange book" is a good place to start, the OG11. For the math section, I'd recommend using GMAT Focus online. It's really helpful; I'm surprised people haven't made more noise about it.

smclean: 10^8 - 10^2 does not equal 10^6. You've just divided instead of subtracted :) To demonstrate: 10^8 - 10^2 = 100000000 - 100 = 99999900. whereas 10^8 divided by 10^2 = 100000000 / 100 = 1000000, or 10^6. What you want to do instead is factor the exponents of 10 ("pull out the tens").

Kaplan has a diagnostic test / book they sell at Borders. I took the verbal section yesterday and scored a 31. I've been ranging 39-42 on other verbal sections I've taken recently. The specific area where I was making more mistakes than usual is the reading comprehension. To answer your question, I ...
