Query: exactly what i needed

I am a student at USU and trying to get into the education program. Professors reccomended this book to study to pass the Praxis iI exam. I was worried this wasn't going to be the right book my professors were suggesting I buy because I didn't recognize the orange cover but it is! Its exactly what I needed to study to pass my Praxis exam!
