This is post exam, but my money was on kerberos (pretty much the only question that was bound to come up). I was also sure we would get a transposition question.
Other than that, I was worried in general. No two past papers were the same, meaning the questions were likely to come from anywhere, and you could not focus on anything at all.
I was also a bit bleak that there were no lecturer solutions provided. The assignment 1 memorandum was good, but I found quite a few errors in the assignment 2 memorandum.
I struggled through about 29 marks which I was basically guessing (albeit educated guesses). Touch and go for a pass I think.
