Record & Track Answers
The core component of this online tool is its ability to time your responses to any question found in the 3 Official Guides. Mark if you guessed on a question and after you submit your answer, click a dropdown list to mark whether or not you want to do the problem later. If you did the problem offline, you can manually enter in your time and answer as if you had performed it at the computer.
Ever wonder what your overall performance breakdown is by question type? View the number of questions you completed in the Official Guide, the percentage of questions you answered correctly or incorrectly, and your average time across all question types. You are also able to view your performance on individual questions, including those you guessed on and those you marked to review again later.
Manhattan GMAT Instructors have written detailed explanations for every quant question in the Official Guide 13th Edition. One Instructor, Horacio Quiroga, even tagged problems that he noticed most students have questions about. "Horacio's Hot List" contains 33 such problems that are extra-tricky. You are also allowed to request explanations for problems you need help with. Our Instructors will see your requests and prioritize new answer explanations based on feedback.
Our paper explanations are the same as our online explanations, but are packaged as a Strategy Supplement. If you are on the go or can't access the OG Archer online, these paper explanations that come with our book will help you receive the guidance you need.
