For P1 and P2, each class will have 30 pupils. For P3 to P6, each class will have 40 pupils.
P3 pupils will be re-allocated to different classes due to the change in class size. We will consider a balanced number of the gender and social mixing as far as possible.
P5 pupils will also be re-allocated to different classes due to subject-based banding, which is conducted at the end of P4.
