The video tutorial covers the 2012 AP Calculus AB calculator multiple-choice section, addressing questions 76 to 92. Each question is explained in detail, covering topics such as the Intermediate Value Theorem, slope of graphs, average velocity, concavity, local maxima, related rates, and Cavalieri's Principle. The instructor uses a calculator to demonstrate solutions and emphasizes key calculus concepts.
