After completing each case, you will be given a grade. If you do 10 attempts on one case, you will be given 10 different feedback scores. All attempts and their scores will be saved for your review. See the image below: at the grading menu, they will be listed by the time of each attempt. You can click on each attempt to view your feedback and score.
For the 1, 3, 6 month subscriptions, you can do each case as many times as you'd like.
