I'm not in your area but I did want to recommend one-on-one sessions instead of a group prep class. Most prep companies will offer both, and of course the one-on-one is more expensive. However, targeted focus on weak areas may require less time overall than a group class that covers everything in equal measure.

Only one I know of in that area is Capital Educators. Well regarded but expensive. Various locations but closest is Stone Ridge. The tutoring companies I know of are all farther west. I’m sure you can find private tutors or use online from the companies. Probably better luck on college board.

I’m looking for SAT prep classes recommendations convenient to Silver Spring/Kensington. Any good experiences to share?
