The idea is helpful; however, the execution leaves a lot to be desired. Printing out the sheet itself isn't intuitive as my group and I have gone through a fair amount of paper and ink at personal expense trying to get a complete sheet out of this pdf. Generally, unless we print it in bluescale, we get fragments of the sheet, consistently. You can't save the data (at least we could'nt, our reader programs would'nt allow for any changes to be saved to the document) so you're literally left looking at colored ink (if you're lucky and it works after re-printing and tweaking the settings back and forth enough to appease the file).

Ultimately, we just hand write down what we need and reference the book.

If you've had a different experience, more power to you. I'm glad someone has.
