I'm doing it again as well
If I just stopped sulking earlier, then I would have noticed that the later work is very similar to COS351, and might have passed my exam
This is a tough course from what I see, however, you need to try and apply logic to the course, it took me a few weeks just to understand the asymptotic orders and how is relates to computer algorithms, keep at it, if you need any assistance I can try and help, drop me an email.
