Why not sign up for the Scottish Mathematical Council Mathematical Challenge which is a problem solving competition for individual pupils in Scottish secondary schools and upper primary schools (mainly P7)?

The competition is divided into four divisions: Primary (P7), Junior (S1 and S2), Middle (S3 and S4), and Senior (S5 and S6).  Each year there are two rounds of problems for Secondary schools and three rounds for Primary schools. Registration of entries and return of marks will be done electronically using the website http://www.scottishmathschallenge.org.uk/
