I was studying the other day using flash cards or index cards and I thought it would be so nice to have an organizer for all of the cards for the different classes I have and I thought of a little plastic container with five slots the outside would be two horizontal slots and the middle would have a verticle slot. From there I thought of other ways that organization would help with this product and I realized another problem I had with studying with index cards. At the end of a midterm I would just throw them out, but when it became time for the final I always wished I held onto them. To fix this problem you could just have 3 plastic cards in each slot so you can put a card in between each midterm so you know what you have to study. Every slot would have a fingerwide cut in it so you could put your finger in it easily.
