I am not a user of Spaced Repetition Systems. I like Random Repetition, not repetition based on a time table set by a system, or by a teacher, for that matter.I do, however, like to review flash cards. I do it occasionally especially now that I can do it on my iTouch. I feel it helps me to focus and it improves my attentiveness to the language. I certainly don’t do it every day. I do it when I feel like it. I read when I feel like it, and listen when I feel like it. I do what I like, when I like, but I do a lot of it. That gives me lots of random exposure to words and phrase. I like randomness because it increases my enjoyment and makes me spend more time with my language studies. I did a video on the subject but I keep getting errors in publishing to youtube for some reason. I will try again and if it works I will post the video.
