The exam simulator has a total of 1,600 questions in 8 exams. Each of these 8 exams have 200 assigned questions. So if you start exam 1 first, and then you go to exam 2 you will NOT see the same questions. But if you start exam 1 five times, then you will see the same questions five times but in a different order.
If I may add, remember to take some time to review the questions in between exams. Revisit the questions that you answered incorrectly, and find out why the the answer you chose is wrong, finally strengthen your memory by rereading that particular concept in the PMBOK.
