All of our students improve on the test. Average improvement is between 150 to 250 points — in some cases even more — and our small classes are catered to your strengths and weaknesses.   



We believe succeeding on the test requires knowledge and practice. Therefore, we focus on teaching the underlying concepts behind the test, everything from grammar and logic to word problems. 



TEST per week

To practice in a test-taking environment, we have students take an optional test every week in our office, which also helps track their progress.


Not your average SAT class. 


No cram zone

Unlike most SAT classes, we don't believe in cramming as many students as we can into a room.

We limit classes to six students, carefully matching each according to level and expertise. Classes are differentiated between beginners and intermediate students — for advanced students, i.e. 1400 and above, private tutoring is the way to go. 

Topics covered include all of the required grammar areas — i.e. parallelism, pronoun-antecedents, and comparison problems — in addition to a complete review of mathematical concepts you'll need to know for the next test.

One of the best courses I’ve ever taken. Oliver is funny and accessible and teaches in a way that makes you want to learn.

These guys are the best. My son, Justin, couldn’t stop talking about how well the instructor explained concepts to him. He kept asking why his school couldn’t do the same.
— Samantha K.
I can’t speak highly enough of this course. It’s completely changed my outlook and approach on the SAT and tests in general.
