All I can say is that computing is a subject in which I hate. I have no idea why I took it, and I have not picked up a book for it. If I get a C at NAT 5, I have winged an entire year of a course. I thought the paper was okay looking if you knew what you were doing in the exam, but for me, it was a hit or miss. Someone who is good at computing tell me what they thought of the paper?
