Will my professor catch me using this?+
Wrong-Answer Drill is a study aid, not a cheating tool. Use it the same way you'd use a calculator, dictionary, or office hours: to understand the work, not to dodge it. For assignments where AI is explicitly banned, don't use it. For everything else (problem sets, exam prep, learning a topic faster), it's fair game.
Do I need to download anything?+
