learning the entirety of CPSC 421 in the next 9 days

Is it doable? I'm basically starting from zero, somehow managed to get 50% on the midterm despite not going to class and barely understanding the course handouts and kinda understanding the textbook readings, but I feel incredibly lost as there are no clear learning objectives and I don't know what I even need to focus on.

Lecture notes are posted but they basically show nothing as far as I can tell. i only attended like the first 3 weeks of lectures and felt like I understood the material less afterwards. mans lectures made me feel like someone slipped some mushrooms into my morning coffee. Only saving grace is the profs exams are very forgiving, he posts practice exams which seem very similar to the real ones, and if your final is your best grade, thats your entire course grade.

Any advice from anyone who has taken the class? I really don't want my horrible decision here to be what ruins my surprisingly high upper year course average lol
