Sometimes you'll see that our subjects double up, like 'Japanese' and 'Japanese language', or 'driving school' and 'driving schools'.
All the subjects on the site are created by users, meaning you can literally learn everything you want (as long as it's legal). What that also means is that we need to build some nice neat ways of saying when two different terms are the same, or related. We haven't got that far yet though, but keep tagging away and we'll sort it all out eventually.
If you're interested in helping out with organising our subject list (we'll be sharing it openly for everyone to use too), let us know!
