Drag & Drop exercise - Score by answer
I've created a drag & drop exercise that requires users to drag items to their correct filing location. Right now, users receive one grade at the end of the exercise-- 100% if they selected all the correct locations, and 0% if they got any wrong (even just one location).
I would like to do one of two things:
1. Grade according to each individual selection. For example, if an item is dragged to the wrong location, a user will receive notification that they've made an incorrect try.
2. If a user makes an incorrect selection, the user will receive notification that the selection is incorrect, and the item will snap back to its previous location.
Any advice is much obliged.
