Title: Great review for Bio Regents
Review: This book was great for my son who was really struggling with Chem-it clearly explained the different topics in an easier to understand format. My only complaint and why I gave 4 instead of five stars is that there was no answer key. What's the point of the test/quiz questions if we can't check our answers?
