I literally saw a person who's been a user since May 2013 and has already solved 300+ problem! Considering at extreme that the person solved every problem for the past 8 weeks, that gives us 8(8+8)=128 problems solved. I also remember that this person is level 1 at the physics portion, so that shouldn't have an impact. In addition, I personally tried the practice problems to see if those problems count and they don't. So how is this possible?
