I just got 3200 XP
I was curious to see how Duolingo teaches my native language (French), so I tried the placement test for French. Obviously I knew all the answers, so Duolingo automatically sent me to level 11 with almost all modules completed, and I got 3200 XP. Then I removed French from my courses, but the XP stayed. Did I accidentally discover a method to cheat?
It's not cheating as you completed the placement test and earned that many XPs by clearing many of the skills. But XPs are separate for each course. So if you earn XPs in say English to French course, it won't add to your English to German course.
