The "I haven't learned this yet" button should NOT be so close to the "Check answer" button because I sometimes press it by accident. It should be further away to avoid accidents.
I think if you have either typed or checked an answer to the question that you shouldn't be allowed to press the 'I haven't learned this yet' button. Seems to be a logical solution to this dilemma.
