Oh I didn't quite mention. It's not bad with flash cards even if you zone out or whatever for a minute or two, you can go right back to where you were.

I also found, personally, that it helps me to focus if I'm having a hard time sort of drawing a circle with my finger around the word/phrase or whatever that I'm trying to remember. (Like, if I'm studying kanji, I move my finger in circles around the kanji with my finger while I try to recall the readings). It kind of focuses me in on what I'm supposes to be paying attention to.
