Hi coffee5251,

We do have the occasional issue where students run out of CAT Exam questions at a particular difficulty level and then the computer algorithm over-estimates their ability level. We're currently working on fixing the problem, but in the meantime, you should take your older exams, run Assessment Reports on them to see which areas you need to improve upon, and then practice those types of problems in the Official Guides. This will be a more effective use of your time between now and Friday than taking practice tests, since you'll actually learn new content that can come in handy on test day.

Best,
