He very well versed in differential equations. I'm currently taking college different to equations and he was able to break down the laplace transformation equations to help me solve/evaluate equation them without using the transformation table and broke it down step by step. Also he was able to solve IVPs using Laplace transformations and broke it down giving indepth explanation. I highly recommend him for College Differential Equations tutoring.
He kept a good balance of instruction and practice, and came to sessions prepared with what to talk about based upon the last session, which definitely made it more productive. Dave is also willing to go above and beyond the session time if there are any loose ends--at one point he sent me a two-page long solution to a problem that we had not had time to finish. Finally, I contacted Dave on short notice and he was readily available and easy to get a hold of/schedule a time with.
He help me go through the practice problems for my Differential Equations Class. We Review Wronkian, Initial Value Problems, Spring/Mass problem, and more. I really recommend him if your struggling with differential equation whether it's for Calc 3 or Differential Equations.
