And then there were none…

I’ve just finished writing my last three exams the last couple of days. It was…actually not all that bad.

On Thursday I wrote the CS 246 final. It was pretty straightforward – a bunch of short answer questions about C++ and software engineering plus a rather large programming question at the end. Considering the last question was pretty much an extension/adaptation of assignment #6 and a similar question on a previous final, it wasn’t too hard. There was definitely a time crunch there though; my wrist was hurting when I was done. :P

Next up was STAT 231 and PSYCH 101 both on Saturday. Ugh. I was actually pretty worried about the former (too much formulae to remember), but the exam was pretty easy. I didn’t like the fill-in-the-blank questions though (-1 for every wrong answer vs. +0.5 for every right answer?) – definitely reminded me of certain Asian exams. :P As for the latter, let’s just say I’m glad it was multiple choice. A lot of questions were just strange and there were plenty of duplicates as well – I don’t think the question generator for the exam was doing too great of a job. Ah well.

What really sucked was that since my last exam was on a Saturday night most of the buses weren’t running anymore. I totally forgot about that fact, but it wouldn’t have mattered anyhow. Bah.

(Oh yeah, so my graph turned out to be relatively accurate. I’d bring up CS 240 / PSYCH 101 a tad and maybe tone down CS 246 / STAT 231. CS 245 gets to shoot through the roof.)

It’s Exam Time!

Wow, last week was just crazy. I didn’t think it was physically possible to complete 5 assignments in a week. :P

First off was CS 240. It was basically an assignment on string manipulation via. the Boyer-Moore and Knuth-Morris-Pratt algorithms. Then we had to manually construct a Huffman tree to determine an encoding sequence for compressing text. Pretty simple stuff, I guess.

Next up was STAT 231. This was basically on model checking, p-value computation (hypothesis checking) and finding prediction intervals. Again, relatively straightforward considering most of the stuff could literally be copied and adapted from the notes… I think I feel a little more confident about statistics now. :P

The two assignments for CS 245 were insane though. I literally spent two days reading through various logic textbooks and notes just trying to understand the material. It actually doesn’t seem that hard, but you wouldn’t think that from attending our lectures. I’ll repeat my quip earlier on Twitter – “University: the place where people make simple things needlessly complicated”. I think I’ll be using that quote for some time to come. :P The good thing, however, is that I think I have a working grasp of what’s going on; that last tutorial definitely helped a lot (the tutor definitely knows how to communicate concepts at a level most people can grasp). I do have one question though. Why were there two assignments due on a single day? It should have been combined into one (this would save about 100 pages worth of cover pages)…

Finally, I had a massive assignment due for CS 246. It was a two-person programming project modelling a soda concession service (with vending machines, students, soda creation plants and more). I have to say, it was actually a lot of fun writing code for this project; I think this was the first thing involving software engineering concepts that I’ve done in university. Perhaps I’d be singing a different tune if I wasn’t interested in or haven’t done any massive projects previously though. In terms of size, this assignment can’t compare to my content management system and I think that prior experience definitely helped a lot. :P (Alternatively, it might be because I got to express my evil side writing code that overcharges people and steals their WatCards/money. :P )

So now that those assignments are done and over with, I have to start studying for exams. Ugh. CS 240 seems pretty straightforward, but I keep wondering whether we’re going to be thrown a curveball on the final (the stuff we’ve done so far seems far too trivial for a second year course). STAT 231 and CS 245 are likely going to be my hardest subjects (with CS 245 coming up this Thursday…). CS 246 will probably be moderately hard, but at least I know what I’m doing in that course. Then there’s PSYCH 101 which I enjoyed but could barely put time into since I was trying not to fail my other courses. :P

Ah well, we’ll see how it goes. ;)
