How to enable strict spelling for my Course

Hi all,

I am trying to create a course about difficult pronunciation for American English. I have two words there, “taxes” and “Texas”. The whole point of the course it to type them exactly correct.

However, when I mix them up, Memrise marks the attempt as “partially correct”. This is not what I want. I want it marked as wrong, so it will show those words to me again and again until I learn to get them exactly right.

Is there a way to do this?

The course is private and only for myself, btw.
