Below are video explanations to some of the math practice questions and all of the Sentence Correction practice questions in the GMAT Official Guide 2015, 14th Edition. Unfortunately, we don't have videos (yet!) for 100% of the questions listed below.
If you find a question without a video explanation, please feel free to add in your own explanation and we will respond with our feedback!
You can purchase the book on Amazon.
