    We haven't started using this book for the kids yet, but I flipped through it and ended up reading the first chapter by myself because I couldn't put it down. The kids are going to be thrilled that Duck is back. I think this is another winner from Life of Fred.

    My high schooler enjoys the humor Life of Fred brings to math. She actually ASKED me to buy this book for her. This is a great way for homeschoolers to earn an elective credit and increase thinking skills.

    This logic book is aMAzing! My husband and I are looking forward to completing it, along with the kids.

    Great Book!

    My son loves math and has been using Life of Fred as his primary math since fractions. He's 16 and going to college full time taking Calculus and Discrete Math for college credit. He is doing this book "for fun" and says it is covering many of the same things his college level Discrete Math class is. Calculus is easy after doing the first half of Life of Fred Calculus and he says this book is making the concepts in Discrete Math easy-- he's been amazed at things other kids are struggling with that were introduced through Life of Fred at lower levels. We are highly impressed with this new book!

    My teen loves this book! I like it because it grows with her (she grows with it?), as it’s a complete logic course for high school (first 6 chapters) and college (all 16 chapters). I’m learning as well!
