I don't know if any of you have used Memrise. It's primarily used for learning languages, but there are courses for all sorts of other things too.
I haven't used it much lately (I use Duolingo now for languages) but when I set about memorising my stack I remembered the site and made a course to help me practice. I have found it very useful so, today, I created a second course for the Aronson stack. If any of you fancy trying it, you can find it here.

I think you will have to create a Memrise account, but it is free and, even if you think my course sucks, you may end up learning a new language or something anyway!

Memrise looks cool. Would be good to have one for Mnemonica.

I used the Chegg iPhone up to create flash cards to test myself.

Memrise is pretty cool. Certainly a great tool for memorizing vocabulary if you are learning a new language (which is its primary function), but I have also found the format is really well suited to this kind of thing, and the course I made for my stack has been invaluable.
That's why a made one for a stack I don't know or use (Aronson), because I thought it might be helpful to others too. I was going to make one for Mnemonica as well but the amount of time required, weighed up against the lack of interest, meant I didn't bother. If there is a chance that it will still be of use to others though, then I may still put together a Mnemonica course too when I have the time.
