Exam Post-Mortem

Was really easy. Alot came from old exam papers. How did you find it?

Unless I made some stupid mistakes, it should have gone OK. Was definitely better paper than that stupid COS261C one...

@hexium

Well, I'll agree with you on the fact that it was easier than COS261C.

Very relieved indeed. Were some tricky bits, but I should pass I think. Much more reasonable than the COS261 paper.

The one question I struggled with, I deserved to struggle with(didn't spend enough time studying the type of question, darnit!). Overall, I enjoyed the exam and subject. The supporting material and tutorials were better than most.

Well I don't want to talk to early but I do believe it went well.

I had 3 question that I was struggled with:

- Question 1 (i) just tripped my brain! A language in the alphabet { a, b} where it have more words of the length 6 then word of the length 7. (4 Marks)
- Question 2 or 3 the question about applying the induction proof. ( 7 Marks )
- Question 9 (ii) about applying the pumping lemma.

But over all everything else should be fine.

For that question 1, I said {aaaaaa,bbbbbb}. Then there are at least 2 words of length 6 in {}* and 0 words of length 7, (2 is more than 0 isn't it ) .
I skipped those specific examples when I went through the induction work (such an idiot - thought they would never ask that specific form...)
They also surprised me with that pumping lemma. Hope my assumptions got me some marks at least.
