Is TutorWyz a one-on-one?

Yes, entirely. Every class is one student with one teacher, and it is the same teacher every week — Priyanka Nakoti teaches the great majority of them herself. There are no group classes and no assistants. We do keep a few other well-qualified part-time teachers, and on an hour Priyanka genuinely cannot make, one of them takes the class from the plan already written for your child rather than the class being cancelled; you are told beforehand who it will be. Siblings are taught separately, though they can be scheduled back to back if that suits your evening better.
