Hey Duong,

Your assumption should not doubt the premise. Your assumption here is just questioning the premise. Accept the premise as fact, then look for a gap between that FACT and the conclusion.

Hey There,

Surprisingly, 50-60% is the normal range of correct answers for all scores between about 500-650, so that's not too weird.

Hey Duong, There are not two options for solving. On all strengthen/weaken questions, you begin by writing down the conclusion and the premises. Then you look for the gap between them. This is not prediction, by the way. This is simply noticing what's wrong with the argument (and something is always...


Hey Duong, Hm. Not sure I quite agree with your point there. Prediction is a double-edged sword, actually. And while it's often very strong on assumption questions, it's not very strong on strengthen/weaken questions. Why? Because S/W questions are allowed to bring in new information, which means th...

Hey Aditya, I'd also add that, when all else fails, avoid expletive pronoun forms if you have a better choice. (E) has that expletive form ("it is becoming harder and harder") and (A) doesn't. Also interesting to note that "one" is also usable as a pronoun. For example, it's inco...


Good luck!

I cannot blame you for that desire. However, the truth is there is no such test. You will not get loads of questions that you have no way of knowing how to solve. If you can recognize every single error on every single question in the OG, that is definitively enough to score very well on the test. I...

Hey BP, You know I love you, right? Because I'm about to get "real" with you (like they used to do on the Real World): This test is not illegitimate or awful or weird or terrible. The prep materials are not perfect but they're perfectly adequate to prepare one for scoring well on the test....

Hey Anastasios, There are two great ways to do it. Either as algebra, or a weighted average: Algebra: X + Y = 300 (because that's total mixture) .1X + .15Y = 38 (because that's the protein) Then, multiply both sides of the second equation by 10: X + 1.5Y = 380 X + Y = 300 Now subtract: .5Y = 80 Y = ...

Hey Guys, You both seem to be missing the symbols above the circles.

Hey Sid, The way you're thinking about this is a common error made by people preparing for the GMAT. Do not try to memorize some infinite list of strange little idiomatic forms. Instead, utilize POE to cross answers off that have more glaring errors. Do I love (D)? Not at all. Is it realistic? Proba...
