@@MlungisiNkosi no it is just that, most of the content on RU-vid that has to do with Maths and Sciences is taught by American and European teachers. Its very rare to find a South African teacher teaching Maths and Sciences, so that's why I said South African teachers really know how to explain when it comes to these difficult subjects. It is because i am used to watching videos of American and European teachers, that I barely hear South African teachers.
