I know auto-accepting only the correct answer is a pretty unorthodox way to do it, but I initially took to making this to familiarize myself with the various syntaxes, and it's the approach I tend to opt for when teaching myself things by rote (notably the Japanese kana and one to ten in all sorts of spoken languages) and it seems to work pretty well. Something about pressing Enter or a "submit" button breaks the neural flow for me; I tend to recall things much more effectively when I become a "constant input stream", for lack of a better phrase. Apologies if it doesn't quite suit you.

It was more the cases where I was wrong, rather than right. Some feedback indicating that the form could not be submitted, and one needed to press "forfeit", would have been appreciated, if only because it is not the way web forms work.

It's a small thing (and I did like it once I realised how it worked) but when doing things in an unusual way a little bit more guidance is required at first.

Enjoyed the quiz!
