For the last seven days, you should try to keep your mind in the mood. For the verbal section, reading on your way to (and back to) work newspapers such as The economist
might help you get back on the ride. For me, it works!
As your problem for the verbal part, do you have any details on the mains areas where you did bad? just SC? if yes, I suggest you take a few hours to go through aristotle SC material, I found them useful, and it might be a good refresher for you.
If you find the post useful, don't be shy and Kudo me
