in the short answers quiz questions if you don't use the exact word but use a word that means the same thing or at least very similar then you got the question wrong. example for my quiz: answer was friction point and I answered friction. even though I technically go it right, the quiz counted it as wrong. this changes the quiz from learning to memorizing exact phrasing.
This is an area where you can stand out because the ai could review the response and help ensure that you are learning. plus it would help build those endorphins instead of frustrating a person cause your score is wrong due to misspelling or not using the exact words.
I also think that the questions should be able to be updated with a regenerate questions button.
