What about the other 5 hours of the day? We have different teachers doing either hurumanu or other activities (P.E, Japenese, Maori, woodtech, etc). Hurumanu classes are your normal run of the mill subjects (Literacy, maths, etc)
Hornby high can be fun with the many opportunities people get in school, things like Cantamath (A math competetion I recently participated in), Air velocity (A car race where you build the car you race in), Epro8 (A engenering competition).
