The questions from the past few days were all easy ones, with a correct response rate of over 80%, which boosted everyone’s confidence greatly. So today we’re going for something tougher to cool things down a bit: lol. Every morning I search for and try to answer the daily question in each section, but I suffer heavy losses – it’s like trying to cross a mountain range. Especially when it comes to fill-in-the-blank questions, I just skip them without explaining anything. As for the questions generated by the system, I haven’t managed to answer any of them yet; P
Same here. I’ll release a daily question survey for the entire area tomorrow
Overedition, you’re cheating – wait until the grading is done before answering on your own;P
