Guys are you talking about "Challenges" section where you play with others or "Quiz factory" where you just rate? Recently I saw many people complaining about the quality of challenges in Rate section, but I guess they don't know that those challenges are not published yet.
I answered a Python challenge just a few minutes ago 5/5 and verified my answers with a Google search to be sure. (Though I don't need it, since I have PLENTY of experience with the language). Guess what I got for a score: 2/5 😬😬😬
Today was bad in Java with the rearrange the lines ones. Which is odd as we mere users lack input in that format. I've no idea how this site earns money but it was feeling like they were farming us as I lost points.
the most of the quizzes are submitted by the peps like you N me... based upon the like of peps like you N me they get into challenges...they may contain errors...but the probability of that is very small
