## McGraw Hill Must Know Reviews in United States

### ***-- "For geometry"
I bought a Must know geometry 2nd edition and the questions in the book are inconsistent to the must know app, which is kind of frustrating because I couldn’t check my answers perhaps ensure that my answers are correct.

In the other hand, the book is good way to start learning about chosen subjects and I recommend it for beginners.

### *---- "Can’t play any audios in ESL for high school"
The audio players in Esl for high school don’t work at all. It’s showing an error. Please fix it
