Parallax – The apparent displacement of an observed object due to a change in the position of the observer.

Do you feel stuck, confused, or lost? Are you studying as hard as you can without getting the results you want? Improving academic performance and increasing test scores often requires that students develop new approaches and apply novel strategies.

Parallax Test Prep expertly facilitates the critical shift in perspective that students need to view problems differently and see a positive change in results. The Parallax approach focuses on customized, fundamentals-oriented teaching that deconstructs students’ understanding, roots out common misconceptions, and provides strategic problem-solving techniques.

Parallax offers students a broad range of elite tutoring and test prep services, including individual and classroom lessons covering standardized tests (LSAT, GMAT, GRE, SAT, ACT, etc.) as well as high school and college mathematics and physics. Parallax also provides expert consulting for college and graduate school admissions essays.

Parallax Test Prep is based in the Dupont Circle neighborhood of Washington, DC and teaches at Metro-accessible locations throughout the District. Instruction is also available via Skype and phone by request.
