A multiple choice bug in Duolingo.
I have noticed and attempted to report this when I first started Alpha testing the Mandarin course a few weeks ago. However, it appears to be in other courses as well.[Disclaimer: I have only checked Mandarin and Japanese so far; this issue is at the least present in these two courses.]
Bug: When one is given 3 or 4 choices for multiple choice, the highest number(either 3 or 4), is never the answer thus reducing the multiple choice down to 2 and 3. This makes timed-practice less effective for learning imo.
This discussion post is just to bring this bug up as reporting in the courses themselves has appeared to be ineffective.
