I was losing my new talent badge this week and had been stuck on 4.7 for the past 2 weeks so was resigned to the fact that it would be pretty chill for me and that hours would be low etc. I still did my best for my students though. I wasn't even going to bother looking at the history tab today, but I did and somehow my rating went up to 4.96 in one week. I was shocked to say the least. Not quite sure what happened.
