How tutoring starts
A plan tied to your test date
Bring an official practice score or complete an agreed diagnostic, then use the results to set priorities for each session.
Stage 1
Establish a baseline
Review a recent score report or practice test by section, then identify the question types and content areas requiring attention.
Stage 2
Build the study plan
Greg maps session topics and practice work to the student’s target score, available study time, and scheduled exam.
Stage 3
Review and adjust
One-to-one sessions address the highest-priority work first, with later practice results guiding the next set of topics.
