Serving our community's youth


Marble Arch Test Prep and Tutoring is committed to our local community. Sensible test prep and tutoring is our mission. 

*SAT and ACT preparation for high school students

*ISEE and SSAT preparation for elementary and middle school students

*Math support for middle school students

*English essay writing tutoring

*Academic tutoring in all subjects

We understand that preparing for the SAT or ACT can be expensive and time-consuming.  At Marble Arch,  we work with students to create a test prep strategy in consideration of their unique goals.  In private tutorials and in small groups, Marble Arch provides expert test prep that focuses not only on test strategies, but in improving reading comprehension, math skills, and writing. In mock tests, we provide complete diagnostic information on strengths and weaknesses.  Large group classes for ACT prep are offered regularly on school campuses. We are proud to utilize custom curriculum created by Summit Educational Group. 

Tutoring is available in many high school subjects including AP courses.  Test prep for high school entrance exams, PSAT, and Subject Tests is also available. 

We work with students of all abilities, including students who receive test accommodations due to learning differences.
