Cardboxes and Zyzzyva

For the first time in a while I have actually being doing some word study. I usually spend about 2 hours each weekday travelling on the train to and from work with laptop in hand I am putting that time to good use.

I have been using Zyzzyva and the cardbox system.

After a little bit of research I found it is actually called the Leitner Cardbox system. Here is a good explaination of how it works.
