    Not great, not bad
    Format: Hardcover
    There are a few sections that are stand-outs. He's a pleasant writer, but over all not much new ground plowed.

    Helped me ace my final!
    Format: Paperback
    I strongly recommend this study guide to anyone who needs to understand and apply the pathophysiology in a final exam. The original book was the textbook for my pathophysiology course- it is over 1000 pages and overwhelming. This study guide broke down the important aspects of each chapter into very doable practice questions. The answer guide at the back has perforations - so I tore mine out and it made it so much easier to follow along and study with this guide. If you are struggling to learn/memorize/understand/apply all the pathophysiology concepts-I strongly suggest using this study guide. It really helped me get through my exam - and I am not a good test taker. Good luck in your studies!

    Helpful for exam preparation
    Format: Paperback
    This is helpful in getting me ready for exams. I fill it in and then study it with my other notes and resources before exams. The activities can be fun (crossword puzzle) or simple fill in the blank. I think I have found 1 or 2 errors that do not match up to the reading but I find errors in the online questions provided with the textbook as well. Helpful to absorb detailed topics. I appreciate that there are answers in the back also so I can ensure I have found the right answer. Love the section that provides hypothetical patient or family questions where I can take the knowledge and put it in layman's terms so I'm ready to explain the pathophysiology in basic terms when needed.
