From our initial contact with BTS, to selecting a tutor and engaging in the sessions, the process was quite professional and delivered the desired result.  David Hung was always on time, and ensured the lessons were understood before moving on to another subject.  We are likely to schedule future sessions, notwithstanding the fact that our son was accepted by his first choice school, in order to keep him sharp.  If your child puts in the time, you will not be disappointed with BTS.
