Yes, everybody gets a lot of questions wrong - at all scoring levels. The same thing will happen on the real test.
Your practice scores may not be entirely valid for a different reason though. How did you handle repeated questions? Also, did you take your practice tests under full official conditions (essays, two 8-min breaks, no use of the pause button, all in one sitting, etc)?
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.
If, however, when you see repeats, you answer correctly even when you shouldn't have, or you take less time than you would have on a truly new question, then you are giving yourself advantages that you would never get on the real test - and those advantages will artificially inflate your score.
