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 has an excellent knowledge of mathematics, which thoroughly impressed me, and helped with my learning of just not differential equations, but concepts in calculus and algebra too. I also appreciated Eugene's attitude towards teaching and his determination to helping me succeed as much as possible. I highly recommend Eugene to anyone who is struggling in math, I had a great experience working with him and believe others will have the same.
This helps learning Differential Equations and Calculus fun as well as for better retention of the subject matter. Doing this helped me re-grasp Calculus and Differential Equations in a much more engaging way than I had in my undergraduate courses I took over ten years ago. I recommend Gary and will continue getting help from him to better understand my course material.
