No problem at all. When you enrol, there are two options: either you are placed in a new group or in an existing group. In case of a new group, all our new students start the course at the same time, with the same background knowledge. If you join an existing group, there's no problem either, as all our courses are structured in such a way that you can join at any time. Our method is based on constant repetition, with 75% of the lessons building on what you've already learned, so your child can quickly pick up the pace.
