Poor score. Suggestions?

Hi guys, I started working on the GMAT 2 months ago on a daily basis. I spend around 10 hours a day on the test prep. I have done all exercises of the following books several times: Kaplan Premier, GMAT 800, and GMAT Review Official Guide. I have also trained with CD-ROMs. But I take a long, long ti...

We know that r is positive and r ² is an integer. Let's take two examples: 1) If r = 2, it is positive; 2² = 4 which is an integer, but √2 = 1.41, which is not an integer 2) If r = 4, it is also positive; 4² = 16 which is an integer, and √4 = 2, which is an integer. Sometimes yes...

I think there's a mistake...

Hi, Here's a DS question that I found in my book: If r > 0, is √r an integer? (1) r ² is an integer. (2) r = m ², where m is an integer. The answer is supposed to be B but I think it's E, right? In statement #2, if m = 1, then r = 1 and √r isn't an integer. But if m = 2, r = 4 an...
