Hi, guys, someone just pointed something out to me and I came here to correct a small piece of misinformation. It's actually not the case that MGMAT CATs automatically give you something harder for the very next question when you get something right or easier when you get something wrong. We address...

They have stripped out only US-centric idioms. (When they first made the announcement, they said idioms in general, but they later clarified that they only took out US-centric idioms.) They have not provided a list of which idioms they consider US-centric, but the list in our SC guide does not inclu...


I don't post on the forums any longer but will answer this one quickly. :) B is the official answer. E is incorrect because it has a pronoun issue: the subject of the first clause is "vocal tracts" and the "they" pronoun later in the sentence is also a subject pronoun, which implies that it is refer...

Someone asked me to weigh in on this - I don't normally post on the forums, but I will on this one. :) Brian is absolutely right that the directions make no mention of needing to preserve the original meaning (and, of course, sometimes the original meaning is actually illogical or ambiguous and need...

More news from GMAC on idioms

Hi, all I just posted this in the comments section of my article, but it's important enough that I wanted to add it here. Larry just emailed me again about the idioms issue. Two very important things (the first from Larry, the second from me): (1) Larry just got back into the office and was able to ...

GMATPrep for the Mac

Hey, all, one other little tidbit I wanted to share from the GMAC conference - they're (finally!) going to come out with a version of GMATPrep for the Mac! It won't, however, be until the next version of GMATPrep launches, in April of 2012. So - no real news for people taking the test before then, b...

Yes, we definitely keep track so that we can fix errors in future printings, and we also post errata lists online so that you can check to see whether something is already a known error. I don't think we have an errata list up for this book yet, but we will soon. If you spot errors in any of our mat...

Er... that's basically what I meant. If you mess up your timing badly enough and don't do anything to fix it along the way, then you'd be forced to guess on a number of questions in a row at the end (or leave them blank, which is even worse). That's not what you WANT to do. It's what happens if you ...

As a general rule, getting 4 to 5 wrong in a row is worse than getting 4 to 5 wrong spread out over some larger number of questions. So the rule is not to have to guess on a bunch in a row, whether in the middle or at the end. (Of course, the only place we're ever really forced to do that is at the ...

coming out of retirement to answer this (note: I no longer participate on the forums - I just write articles) :) approximately 3 percentile points per question for leaving a question blank. gmatmachoman is correct that you can't give an exact answer to that question, because it depends upon things l...

GMATCreature, you make many very good points. I should point out that, when I say those of us who score 780+ don't need to do all that much, it's not because we have a magical, innate ability to figure anything out in 60 seconds. (I also want to point out that we are talking 780+, not "merely" 99th ...

In general, I agree - for the very top schools, they tend to prefer a balanced set of subscores to a skewed set. There are a lot of schools that don't examine the subscores at all, but for those who do, generally speaking, balanced is usually preferred.

I'm a little confused - did I get the numbers wrong? According to what you wrote above, you had 16 questions wrong on GMATPrep and 25 wrong on MGMAT - a substantial difference. If you answered 25 incorrect on GMATPrep, your score also would have been much lower.

If you make a lot of careless errors on questions that you would ordinarily get right (which you said you did), that's going to change your score quite a bit. If you had timing problems (which you seem to say you did) and you get a lot of questions wrong in a row (especially at the end), that can dr...

Quick reply but FYI I'm no longer participating on the forums (though I do still write articles for BTG). For future reference, please contact Ron Purewal and/or Whitney Garner for any MGMAT help on the BTG forums. We do not include experimentals on our test and we believe that GMATPrep does not hav...
