My son says you are able to explain in a way he can understand. Forewent going to a free tutor because he prefers how you explain.
She was friendly and helpful.
She really made you work hard and gave you problems [...] to work on. The problems would be about the topic you are struggling in to make sure you understand the concept.
[Enjoyed the] personal one-on-one attention.
Tutor was extremely prepared prior to the session.
