This forum letter (see link) laments how primary school teachers are made to teach all subjects and sometimes may be inept at teaching the subject they are not trained at.
This is why at the Study Room, Wei and I work on our forte to provide the best education for our students . We also always attempt the exercises we give our students to ensure they won’t be confused by badly-set questions.
Since I am a Physics and Maths graduate and Wei depends on English for his livelihood, we focus on building the foundation for our children so that learning’s a breeze for them in secondary school.
