Hello, Jonathan. The questions in the annual OG, Verbal Review, and Quantitative Review are unique to each source, so you will
not see the same question if you jump from one resource to the other. However, many questions are carried over from one year to the next, so it is quite possible to see repeat questions that way. In addition, sometimes a question appears identical but differs slightly from an earlier iteration. In
boldface CR questions in particular, I have noticed that several passages will have two or even more versions that use the same passage but highlight different areas of text. (I even had a student who recently told me that he recognized a CR passage on the actual exam, only the question stem had changed to or from a boldface question.) Meanwhile, SC questions almost never recycle the same sentence, RC questions are specific to their own passages, and Quant questions also do not receive cosmetic changes before being given a second run, especially not in the same year of official guide publications.
One final note: If you are practicing through Wiley, make sure you select only unanswered/unattempted questions from the dropdown menu when you create your practice sets; otherwise, you will see repeat questions.
Good luck with your studies.
