quiz feedback

I'm using 7.x-4.0-beta2 and would like to provide quiz-takers with "instant" (same page as question) feedback. I've done a bit of jQuery in Drupal, so I can probably figure it out eventually, but if I had a nudge in the right direction it would save me a lot of time.

I assume I would need to add something to, e.g., Drupal.behaviors.multichoiceAlternativeBehavior

such as adding something to
.click(function(event)

?

Or maybe I could use the .addClass('selected') to trigger showing

$content['body']['feedback']['#markup']

???

Suggestions welcome. Thank you so much.

I am an instructor in an on-line course. When I use Quiz, I have to turn off the feedback setting because I do not want my students to see the feedback until ALL the students have taken the quiz.

I also use manual scoring to avoid having students see the correct answers before everyone has taken the quiz. But - when I use manual scoring I lose the ability to show students the correct answer. And when I turn off the feedback setting, I lose the ability to explain to the students why they got something wrong.

Is there a way to control the time when feedback is provided so that students see the feedback AFTER I've scored the quiz?

Is there a way for me to manually add comments and provide feedback when I'm scoring a quiz?

I really like the new Quiz module, thanks to the people who put in the hard work to make it happen. Is there a way to provide user feedback on short and long answer questions (after each question)?
