Hello, Neeraj,
Due to the confusion that I see in some of the responses, allow me to clarify this. We have 1,610 questions that are organized into 8 exams as follows: 7 full-length 200-question exams and 1 exam that is comprised of 210 pure ITTO questions. All questions are unique, and if you attempt full exams, you will never see the same question in two different exams. This is because each exam has 200 dedicated questions. The only randomness you would see if you take the same exam more than once is the order of the questions. For example, if you take Exam #3 for the first time, you will see 200 unique questions ordered in a particular way. However, if you take the same Exam #3 for the second, or third, etc. time, you will see the same unique questions, but just organized differently. For example, question #1 in the first attempt may become question #159 in the second attempt and #27 in the third attempt. In other words, the sequence of the questions will change every time you take the same exam. But the questions themselves remain the same and, as clarified above, unique for each exam.
Quizzes, however, are designed differently. They take questions from the same 1,610 question pool. So not only may you encounter the same questions in every new quiz you take, you would definitely encounter these questions in the exams. Therefore, we recommend using quizzes lightly to avoid the effect of memorization when you encounter the questions while taking full 200-question exams. There is an option in the quiz mode, however, to select unanswered questions. This would at least eliminate the chance of seeing the same questions in the quiz.
I hope this clarifies the subject.
