If you asked me where I learned my countries in Africa, I’d tell you that it was from watching Where In the World is Carmen Sandiego? My knowledge of state capitals? Animaniacs. My ability to find prime numbers while being hunted by cartoon monsters in a 6×5 grid? Number Munchers.

And while these and so many other skills that I learned in school also came largely from my grade school teachers, I think that there’s an underappreciated value to using videos and games to help supplement learning. Staring at a GMAT book for an hour isn’t helpful if you aren’t learning anything because your mind is checked out. But tricking your brain into getting faster at finding numbers that multiply to 24 might be, especially if you can make time to do so on your ride to work or while waiting for your dentist appointment. And for many of us, myself included, there’s no better place in the world to find 5-minute distraction than at the App Store. So if you have an iPhone or iPad (and many of these apps are also found on Android too) check out some of these apps below. And if you have any other apps that you use, type them up in the comments below!

The other week, we discussed the overall process for Data Sufficiency. This week, we’re going to test out the process using a GMATPrep question “ and take a look at a couple of very common DS traps.

Set your timer for 2 minutes. and GO!

*  A bookstore that sells used books sells each of its paperback books for a certain price and each of its hardcover books for a certain price. If Joe, Maria, and Paul all bought books in this store, how much did Maria pay for 1 paperback book and 1 hardcover book?

(1) Joe bought 2 paperback books and 3 hardcover books for $12.50.

(2) Paul bought 4 paperback books and 6 hardcover books for $25.00.

Note that I haven’t listed the answer choices for you. Because DS answers are always the same, we should memorize them. If you don’t have them memorized yet, look back at the How DS Works article linked in the first paragraph.

All right, let’s tackle this problem.

Step 1: Read the Question Stem

The first sentence tells us that each paperback book sells for the same price and each hardcover book also sells for the same price (but possibly a different price than the paperback books).

The question asks how much Maria paid for 1 of each type of book. Is this a value or a yes/no question?

They’re asking for a specific amount; this is a value question. We’ve also got lots of words; we’re going to have to translate.

My title is a little odd there “ why the very specific timeframe? Well, we know that business schools aren’t using the Integrated Reasoning (IR) section much (if at all) this first year, for admission in the fall of 2013, but we also know that IR will probably become more important over time.

How much more important? Nobody knows, but it’s a good guess that the process will be fairly gradual. We have decades of data for the quant and verbal sections, so the schools can feel confident in interpreting that data to help make admissions decisions. After the first year of IR, we’ll still have only one year of data; as a result, it’s highly unlikely that IR will suddenly rise to the same level of importance as quant and verbal.

So what should you do if you’re taking the GMAT sometime this year in preparation for a fall 2014 start? How much attention do you really need to pay to IR and what kind of score will be good enough?

Here are the current percentile rankings for the 1 to 8 IR scoring scale:

Here is this week’s problem:

A regular octagon (a polygon with 8 sides of identical length and 8 identical interior angles) is constructed. Next, an equilateral triangle (with sides identical in length to those of the octagon) is attached to each side of the octagon, such that each side of the octagon coincides exactly with the side of the triangle. Finally, each triangle is folded over that coincident side onto the octagon, covering part of the latter’s area. Approximately what proportion of the area of the octagon is left uncovered?
