yes of course...you need to add it the questions when you build them

I have done that, but when the test is submitted is when all the feedback floods in for me and the learner has to re-enter the test to view it. I am looking for a submit of each question and instant feedback on that question only

If you allow them to see the answers at the end of the test, they can see it there immediately after they completed the test...you cannot display the feedback after each question is submitted unfortunately.
