They have so frequent module tests for Maths, the teacher could definitely know the level of the kids. I remembered once when they found that the result of module test for particular topic was not good for all classes, the teacher had retest the same topic after reinforced the understanding of the kids. So, no need to worry.
Is your kid P2? I remember during one long week end a few week ago, the teacher asked to do 2 chapters of Math supplementary exercise which had more than 40 questions each. They should have a policy of not more than 15 mins per subject. That was not the only Math homework on that week end. Not sure if some parents had already reflected to the teacher, these two weeks are a bit better.
As observed that the workload of G2 is much more than expected, particularly on Chinese! How can we channel the situation to school as the major reasons for choosing WKF were their teaching mode and lesser workload from subjects. It is seemingly the workload is same as government schools.....rather disappointed!
