I believe that sometimes learning the most difficult material sometimes requires going back to the basics as a reminder. My range of what I teach can go from basic word problems to Calculus, Discrete Math, & Probability. English classes that I teach range from basic grammar, to AP Rhetoric and English Language (as well as Literature). Science material have wide range with Biology and Physics, too. I studied at Carnegie-Mellon, Rutgers, and Columbia University. I have tutored professionally now for 25 years. My name is Michael King and I approve this message (LOL!)
