Im planning on taking both the fall tests, and am building my study plan around rereading chapters and doing end of chapter problems from HRW. I am curious as to how people, who used this book in their own gre studying, chose which types of end of chapter problems to focus on (ie just the 2 or 3 dot problems, just the SSM problems, etc). I certainly wont have the time to do every single end of chapter problem in the book, so i'd like to come up with some general guidlines to pick and choose the problems that will likely be the most beneficial (or at least most beneficial/ hours spent stuying) to my test preparations.
