Discrete Math 1 is now updated to have all lecture videos linked. All videos are now available, except the last which will be available on January 6, 2015. I might create a midterm/final in LaTeX and upload solutions just for the sake of having a cumulative exercise available. Not many Discrete Math courses from universities have final exams available online, or they cover slightly different material. Everything will come together after Discrete Math 2, though, when I have more to choose from.
