dapplegate is right that, if you have improved significantly, then questions will be selected from a higher part of the pool on practice tests. It's not clear to me, though, that this is youngrae's situation. It sounds as though youngrae might not have seen a big increase so far.
youngrae, you can still take both GMATPrep and MGMAT CATs with repeats as long as you follow a few guidelines to minimize the chance of artificially inflating your score via question repeats. First, anytime you see a problem that you remember (and this means: I know the answer or I'm pretty sure I remember the answer, not just "hmm, this looks vaguely familiar..."), immediately look at the timer and make yourself sit there for the full length of time for that question type. This way, you don't artificially give yourself more time than you should have. Second, think about whether you got this problem right the last time. If you did, get it right again this time. If you didn't, get it wrong again. If you *completely honestly* think that you would get it right this time around if it were a new question (even though you got it wrong last time) because you've studied that area and improved, then get it right this time.
More importantly, how often are you taking practice tests? I'm guessing way too often. CAT exams are really good for (a) figuring out where you're scoring right now, (b) practicing stamina, and (c) analyzing your strengths and weaknesses. The actual act of just taking the exam is NOT so useful for improving. It's what you do with the test results / between tests that helps you to improve.
It's pretty much never a good idea to take a test more than once a week, and even that situation is reserved only for the last 2-3 weeks before the official test. Prior to that, most people need at least 2 to 4 weeks from the last test in order to make enough progress that they can see any significant difference on a practice test.
