Well, as long as you can do something beneficial with it, then it will be great, and as you say, it will also refresh your memories. I am one of those, that as soon as I have conquered something, then I just allow it to slip away. So, if it suits you, then dust them off, delve into them and do your thing. Hopefully it will be of benefit for some in the education field. I say hopefully, as many don't like to read anymore these days. !LOL
