Adding to @kquinn: I love the return scores option, but I wish that I can choose which questions I want to return scores. Often, I mix short answer with multiple choice items, and returning scores instantly on multiple choice is not wise for obvious reasons. =) However, I love returning scores on short answers. Wish list?
This is an interesting idea! Another feature we are currently considering is giving you the ability to limit the number of student attempts allowed for closed questions (ex: Multiple Choice, Multiple Selection). Would this meet your needs or is there another reason you’d like to return scores for short answers questions independent of other ones? We are discussing this in this thread if you want to check it out:
