Sparky, the one thing I use now is OneNote. You have it on the tablet and you can amend it as much as you want and you don't have to print out any paper.

It's like having a notebook. The EFB version is not the full version of it but it does the trick. You can create a subject like Limitations, another Memory Items, another systems and so on. Keep it simple so it's just a quick review and it's always there on your tablet.
