This page lists video explanations to all of the 215 questions in the quantitative database of questions that are part of the older GMAT Official Practice Exams 5 and 6. These tests were earlier called Exam Pack 2 and were originally released in March 2016. I have organized the problems by subtopics and included the first sentence of the problem statement. Please use the site search or page search using the browser (Ctrl+F) to locate my video explanation of a specific problem that you may have encountered in your practice tests.
