Rules of Contests
We offer 5-6 contests per year. Each contest is graded individually, and then at the end of the year the Year Winners are also selected as a result of their cumulative scores.
Winners are selected by grade level (i.e. there are separate winners from grade 2 and grade 3 even though they are offered the same contest).
It is important that contestants show their solutions. A correct answer without an explanation is awarded 50% of the possible points. Only a correct answer with correct explanation will lead to a 100% score. Partial explanations result in partial scores.
Note: only MWSM students and their relatives
are eligible for the prizes – although of course everyone
is welcome to send solutions.
