GMAT Online Question Bank: Question IDs

The online question bank that corresponds to the GMAT Official Guide 2026-2027 uses Question ID# to organize the questions. If you are using the GMAT online question bank then you would need to know which question ID# corresponds to the questions in the physical GMAT guide to find my video explanation. The information below lists the question numbers in the physical GMAT guide along with the question ID# in the parentheses. Also, please note that in the official guide both question number 92 and 101 in the quantitative reasoning correspond to the same Question ID# of 101041, this is likely a typo from GMAC.
