Postpone your test. This is not fixable in one week and major timing problems mean you don't know whether you're going to have a good day or a bad one when you get in there.
Plus... maybe something's weird with the dates, but you posted on May 30th, said your test is in a week (which would be around June 6th), and seemed to indicate that that test will NOT be with IR. The last version of the test that did NOT contain IR was given on June 2nd, 3 days after your post. From June 5th (tomorrow) onward, the test will contain IR. (The test was not given for 2 days to allow them to switch the software over.)
So... either something was miscommunicated or you are actually signed up for the IR version...
Okay, next, I assume you want some help with the timing issue, right? :)
Read these two articles; start doing what they say:

Next, since you're going to need to prep for IR, start here:
http://www.manhattangmat.com/blog/index ... reasoning/We also have multiple additional articles on our blog - you can browse for them as you prep. We have a workshop video posted that will orient you to the section and question types - you can watch that for free.
We also published an IR book about a month ago. If you took our course, then you can get a copy of this book at a steep discount - contact our office (800.576.GMAT or
studentservices@manhattangmat.com) for details.
Finally, please do continue to use the forums as a resource - just FYI that the forums aren't the place for urgent last minute questions. As you've seen, you'll often wait 3-5 business days for a response...
