Okay so this year is actually my 10-year High School reunion, not that I am going but it made me think. I mean I honestly don't remember half of what I learned and I was actually a decent student. Well the book "I Used to Know That: Stuff You Forgot From School" by Caroline Taggart is a book that is perfect to brush up on facts and subjects you may have forgotten or are remembering wrong.
In "I Used to Know That" you will find a variety of subjects, covering English, Literature, Math, Science, History, Geography, and General Studies. It is basically a quick book to reference to re-discover lost knowledge. I even love how this book looks like a school ledger, but it is hardcover so it will last. I cannot believe how useful this book is and how much I pick it up. Honestly, I find myself flipping through it all the time and always learning something new, even though this is only a 175-page book.
I re-learned about the planets, famous composers, wars, the circulatory system, geometry and so much more! I really think this book is adorable and perfect for anyone who is either currently a student or someone who wishes maybe they can remember more of what they learned in school! This book is classified as a Reference/Trivia book and is a Reader's Digest book.
