I am a guy who scores decently on verbal sections but has problems with quant. I recently had a school tell me they will give me better consideration if I can get a higher score on a GMAT retake. I have less than a month before my scheduled exam and am in search of a source (either free or for fee) that has a nice neat consolidation of various types of quant problems--for example "work", "sequence", "coordinate geometry", etc. I'm looking for a source that would contain at least 50 each of such categories--I want to get really acclimated to each general question/problem group. I love the stuff here on some of the posts, but I'm very busy and even more math challenged; my brain gets tripped up looking at post after post with 1-5 questions each.
Any suggestions on one comprehensive motherload of such material would be greatly appreciated!
Thanks!
