Tutor you in Math or Computer Science for 30 minutes-1 hour - virtually over Skype or in person (if you're in Palo Alto). Ideally, you would provide a few problems to work through beforehand, though I can also build my own/walk through concepts.

My math coursework: Single Variable Calculus, Multivariate Calculus, Linear Algebra, Differential Equations, Probability, Stochastic Processes

My CS coursework: Introductory programming in Python/Java/C++, Theory of Computation, Natural Language Processing with Neural Networks, Web Applications, Computer Systems, Algorithms
