I have worked with students to prepare for the SAT, ACT, ISEE, SSAT, GRE, and (less frequently) the ASFAB and SAT II Subject tests.
Standardized Test Prep is (fittingly) relatively standardized. I personalize the experience as much as possible, however, focusing on understanding the material and the test format rather than memorizing “tips and tricks”. Successful test prep—as any of the big companies will tell you—also requires significant student time outside of tutoring hours, though I can customize a course to fit any reasonable goals and schedule.
