If you are teaching yourself with this book, I hope you have other aids along the way! If it hadn't been for my brilliant Hebrew professor, I don't think I would've found this book to be at all accessible. Not to mention in some chapters toward the end there are some not-so-trivial errors. Definitely a good side resource, but I wouldn't make it my primary.
Counting this as something I read because I spent a LOT of time studying with this. super helpful! My professor that used this book was actually a student of Dr. Ross and she was right about how brilliant he is! I love all the tools he includes in the appendices. The exercises and translations were helpful too. Pro tip: if you have the answer key, working backwards was also really helpful in the English to Hebrew stuff. Overall, this made studying Hebrew easier. I like how the verbs and such were structured! Then it gets into Scripture which is soooo fun!
