The third iteration of the practice tool design includes designs based on the second iteration but with new additions. We added an option to choose communities to learn from, feedback for the user to see what questions they got right and wrong, and a new sidebar that expands into the leaderboard. We also added emoji feedback for each practice question for the user to rate the question they just answered. We also rethought how the progress bar would look at the top and added user points along the horizontal bar.
