I'm taking the GMAT next week and I've consistently scored in the 670-690 range on practice tests. In terms of what I need to improve on, I'm all over the map - verbal will go way down one week, math the next, I'm really not sure what I'm doing wrong. If anyone has any ideas on what I could be doing differently (more practice tests) to bump up my score just another 10 or 20 points, please let me know.
During the last week of my studies, I simply went over my weak areas and redid the easy and medium difficulty questions - then I studied them again and again while looking for different permutations of the easy/medium questions in different cats I've taken etc. This allowed me to get those weak areas that were previously dragging my score down right 100% of the time, which made it much easier to break the 700+ barrier.
See my entry about "quant complexity" near the end of the blog found in my signature. I detail the process I used to go from a high of 45 Q in the week preceding the GMAT to 49Q on the real deal.
