Do you recall any specific types of problems that gave you the most trouble? Were there problems that you just didn't know how to do? If you can remember the most troublesome areas, then you can focus more on those areas in the upcoming month.

It seems like you may have had the most trouble with timing, so if you can get the timing pinned down, that in itself could help your score quite a bit. From what I understand from reading the posts from the really high scorers here, everyone has to guess at some problems, but you want to make sure that you are guessing at the problems you really don't know how to do or that would take too long to do instead of missing the easier ones just because you're running out of time.

Nice job on the verbal! Just because you're International doesn't mean your verbal can't be good.
