I really like Prep1 on 1. They are located in Cabin John Shopping Center on Tuckerman. All sessions are one on one - its highly tailored to the child's needs and schedule - and there is no set number of sessions. My DC has really liked the tutors so far and he's not bored.

Prep Matters in Bethesda is awesome. DD both in person and virtual for ACT prep and she saw a huge improvement.

Looking for some good options for PSAT/SAT prep courses in the Rockville area or nearby. Needs to be in person, and can be one-on-one or a small group. Willing to spend a fair amount of money, but only if the quality of really high.
