This Fraction Problem Is Harder Than It Looks

by

I’ve spoken with multiple students lately who received a disappointing (lower than they were expecting) score on the quant section and who all said that the quant felt relatively easy or straightforward. How is that possible?gmat factions

First of all, thinking that a test like the GMAT is easy is actually a warning sign: things probably are not going very well. If the test was going very well, then you’d be seeing some seriously hard “ next to impossible “ problems.

Second, the test writers are phenomenal at writing questions that don’t seem all that complicated but are in fact your worst nightmare. My worst nightmare is not an impossible question “ I know I can’t do it, so I just pick and move on. My worst nightmare is a question that I think I can do, and I spend a decent chunk of time doing it, and then I get it wrong anyway “ even though I’m sure I got it right!

Try this GMATPrep problem and you might see what I mean. Set your timer for 2 minutes. and GO!

*  Of the 3,600 employees of Company X, 1/3 are clerical. If the clerical staff were to be reduced by 1/3, what percent of the total number of the remaining employees would then be clerical?

 

(A) 25%

(B) 22.2%

(C) 20%

(D) 12.5%

(E) 11.1%

What’s hard about this one? It looks completely straightforward!

Hmm so I have 3,600 employees and 1/3 are clerical. That’s easy: 1,200 are clerical. Then I need to take 1/3 of that, so that’s 400. They want the percent of the total, so 400/3600 = 4/36 = 1/9 = ugh. Let’s see, a little quick long division right, 1/9 is 11.1%. Answer E. Done!

Where’s my mistake? Go find it. (Actually, find both of them.) Also note that my wrong answer was right there in the answer choices!!

My Deadline is Approaching and I Don’t Have the Score I Want!

by

I’ve been speaking with a lot of students in this position recently “ welcome to December. Most second round deadlines are rapidly approaching and some students, unfortunately, don’t yet have the score they want in order to apply. What to do?

What you CAN’T do

gmat deadlineThere are some things you can do “ but we can’t expect miracles either. If you tell me that your test is in less than 2 weeks and you need to improve your score by 100 or more points, I’m going to (gently) tell you that such a goal is unrealistic. I’m not going to discourage you from going for it (it doesn’t hurt to try), but you should also start examining your other options are. These could include accepting your lower score, changing the schools to which you apply, or postponing your candidacy to a later round or a later year. Some people, thinking through this, actually end up deciding that they’d rather wait a year anyway and take their time with the whole application process.
