Query: Awesome study cards!

I just recently purchased the Wisebridge Learning Systems Physics Flashcards and they are absolutely great. These cards beat any other physics flashcards on the market. I highly recommend them to anyone either taking physics classes or preparing for the MCAT. I have my B.S. in physics and I wish the cards had been available when I was studying physics. The cards don't just have you memorize a bunch of facts but instead they help you to actually think about physics. These cards are great!
