Award-winning Harvard PhD tutoring Test Prep and STEM subjects. As a Harvard Ph.D. with a B.S. from the College of William and Mary (Phi Beta Kappa, Summa Cum Laude), I know exactly how to help students with their STEM courses and standardized test preparation. I have a track record of successfully helping students with their courses and standardized exams. I most commonly help students prepare for all sections of their ACT, SAT (including the new digital SAT) and ISEE/SSAT exams, as well as with STEM courses such as AP Biology, AP Calculus, AP Chemistry, data science, machine learning, AI and Python.
