Am using this to refresh my high school Physics and Chemistry (that was over twenty years ago now!). I was worried this book may be a little on the basic side, but so far is proving great, getting me back to a level where I don`t mind Googling for more advanced information.
The diagrams are really helpful and makes it less of a dry read.
