Mathematics is the queen of all sciences, dear!!!You can fill it just the way a guy who loves science does.To be more clear, you can add details of exams of mathematics which you have qualified, like the RMO(Regional Mathematical Olympiad), even those SOF ones (even though you should not give it more priority), things like mathematical quizzes or mathematical projects, seminars, or cases where you took classes.Anything.They test more of your confidence and attitude than your knowledge.They will ask twisted questions to test the depth of your knowledge.P S: I had my interview today only.
