So, here's the thing. Last week I had not attempted any Geometry & Combinatorics problem. But, I was taken by surprise this week when I realised that I have been levelled down.
In the email that I received from Brilliant today, there were links to problems that I had tried but didn't get last week (whereas I had not tried any). Also the links lead me to a page showing that I have tried 8, got 5 correct and 3 wrong. On the contrary, when I click on the "Solutions" tab it shows that I had not tried any problems last week. Also the problem sets are different.
I think there has been an unintended mistake. Please fix it as soon as possible.
