I understand where you are coming from in regard to the Numbers Properties book. It isn't exactly going to be a direct relation in questions you will likely face on the GMAT so much as understanding the underlying principals of the questions. What this means is that understanding the properties of the numbers in the GMAT questions allows you to better understand what they are asking and also how to use the strategies in the
MGMAT books to solve the questions. As an example, if you are asked to find some number, the question says it's an integer (or prime, or even, you get the idea), you can take this and, with your understanding of number properties, quickly eliminate some of the answer choices, or to just quickly calculate the correct answer. I have found that I am doing questions so quickly that I'm starting to wonder if they are really asking me what it looks like. I'm starting to doubt myself as the answers are sometimes coming so quickly that I don't even write the information down. It just pops into my head. Keep in mind that this was NOT the case 6 weeks ago when I started studying. Back then I was writing copious notes and calculating everything. As others have posted on here, the Numbers Properties book is incredibly useful.
Also, I'll be honest and say that some areas are still difficult for me. I answer the advanced probability questions correct only part of the time. This is also true for combinatorics. I can only invest so much time on each area so I'm happy that I have a strong grasp of almost all of the topics. As you can see with some users, they scored high even when there were a couple sections that they were weak in. Good luck![/quote]
Vince,
So have you taken any CAT's since you've started to figure things out quicker? I'm trying to see the correlation between what you've learned from your starting point. It sounds like you're almost ready to schedule your exam, no?
