This seems to have been an easy IMO (except problem 6). Problems 1 and 4 were very easy, most likely due to smaller countries rallying for easier problems. Problem 2 could be brute-forced, and problem 5 was clearly misplaced (everyone on the US team got a perfect on this question). The consensus does seem to be that the geometry problem 6 was very difficult. So it's not too surprising Alex got a perfect.
