Love the username! I might get in trouble for this but you could also consider a nod to Death Row Records with "GMATsUpHosDown" too...
One quick note on your strategy - unless you haven't studied for very long at all, I'd argue that within that last week it's tough to "get smarter". Today, tomorrow...you can learn some new things. But the day before your test? You only risk wearing your stamina thin or wrecking your confidence by stressing about something that you're struggling with. I'd say that your emphases this week should be on:
1) Minimizing mistakes. Here you CAN really improve because you want your common mistakes to be top of mind on test day. Do take a practice test this weekend, but don't dive right into a quant set immediately after. Take time to determine which questions trapped you and WHY they did. Any silly mistakes that you tend to make or systematic mistakes (assuming something about a variable; answering the wrong question; etc.) you can probably eliminate by just noting those on your noteboard during the test and making sure you hit that "common mistakes" checklist.
2) Reminding yourself of what you do well. Think of the thought processes that lead to success for you and drill those into your mind. "On DS I need to try to determine how to get the OTHER answer"; "for Strengthen questions I need to pause to really understand the conclusion"; etc. Focus on the thought process and that will be your guide on the test.
3) Maintaining confidence. The above strategy helps because you're reminding yourself that you do do most things well. And I'd stay away from new problem sets the day or two beforehand so that you don't accidentally hit that rough patch of monster questions that makes you doubt everything you ever knew.
4) Resting up. The GMAT is an endurance test - you'll spend over 4 hours at the test center. Don't do any heavy lifting the day before. Relax your mind, get some sleep, and remind yourself that you've worked hard for this...test day is the victory lap!
