hi,
my advice is - if you're running out of time on the real test - guess all of the remaining questions, because you're not getting penalized for guessing wrong, but there is a penalty for leaving quesitons blank. you'll be better of by guessing 7-8 quesitons [which is too many but beats not answering them], this way, you still have a chance of getting some of them correct, compared to leaving them blank which assures 100% penalty. work on your time managment tactics and good luck with your prep. hope that helps
