Online Question Bank: Quantitative Reasoning
Starting with the 2021 GMAT Official Guide, the diagnostic test of the older GMAT guides has been repurposed as an online bank of test questions. The 48 quantitative reasoning questions, 24 Problem Solving and 24 Data Sufficiency, can now be only accessed via Wiley’s Efficient Learning website. I have organized these 48 problems in the order in which they appear in the online question bank. This order is different from how they originally appeared in the diagnostic test of the 2020 GMAT Official Guide and older editions. I have also included the Practice Question Identifier or PQID in the video explanations. This PQID appears below each question in the online question bank and you can search the website for this PQID to locate the corresponding video explanation.
