Is 3599 prime? (And why or why not?)

Well, David, [spoiler]3600 is 60².
So 3599 is 60² - 1 = 60² - 1² = (60 + 1)(60 - 1)
So 3599 = 61 * 59. Not prime.[/spoiler]
Nice question.

I have to assume that you are comfortable enough with DS questions and most of the Quant concepts that appear on the Test. Do you have a formal "process" for dealing with DS questions? Are you looking for one? You mentioned something in your last post that I'd like you to explain further. When you say that you get DS questions wrong because of a "lack of understanding", what do you mean? Since you've been studying for about 2.5 months, and you scored a Q46 on your Official GMAT......!!!!
