Half price for first-time clients! I'm a graduate from Penn State in math and computer science, I have experience as a private tutor for a Penn State tutoring company, and next year I'll be starting on a PhD in mathematics at U.C. Berkeley. That is to say, if you need help with math or computer science, up to and including undergraduate level coursework, I can help get you up to speed. Happy to work over instant messaging or over Skype.
