Whats up everybody, I'm new to this site, and I plan on taking my GMAT in mid Oct. I've been using the Official Guide as my sole study source, but alot of people I know that have taken the GMAT has stated that there were probability and combination types on the test, since I've never taken a descriptive statistics type class, I'm fearful right now of these types of problems especially since I gone through the Official Guide from cover to cover, and there isn't that many combination type problems in the book.
I saw the Kaplan 2004 guide in the store, and I was wondering if this book is worth the $32 bucks and does it have combination and permutation type of problems in it?
Thanks
