I thought the PR Cracking questions were really good, and on par with what I saw on the real thing.
Since you're off for the week, spend a few hours in the morning doing practice questions for each type, a block at a time. Maybe do just verbal in the morning. Then take at least an hour break to mentally and physically recharge. Go for a walk or a run, eat some lunch (protein, not primarily carbs so you stay alert), get completely away from a desk and computer.
Then, in the afternoon, do a different block of questions, say all quant, for 2-3 hours.
Then take a longer break. Do something mindless, like laundry or cleaning. Stretch out. Watch some tv or read the paper while you eat dinner. Change your mental and physical focus for a bit. That can help you keep your stamina on such a grueling cramming schedule.
Eat a good dinner with a decent amount of protein (chicken, salmon, tuna salad) but at least some carbs to sustain you. Take a full, timed practice test, and compare how you did to how you were doing on your practice questions earlier in the day.
The next day, focus more of your time on the problem areas you saw from your test the night before. If you were getting certain problem types right during your practice sessions, but not getting them right on the timed test, then review the strategies in your Cracking book and work on timing, process of elimination, etc.
Do this each day, gradually working through weaker areas. Just don't abandon altogether stronger ones, so that you're still sharp on those on test day.
Good luck!! Let us know how it goes!
P.S. Definitely do the practice questions in the
OG. There are more in there than any other book, and they're the best ones. Between PR and GMATPrep, you'll have plenty of tests for the week.
