Week 5 and Term test
Treated more of the golden ratio, turns out it has an unexpected connection to fibonacci numbers. I honestly wonder how people sit down to figure this stuff out and come up with endless theor(ies/rems) and formulas. Well the numbers make a whole lot more sense, or do they? There was more on unwinding recursions, not really much to say about that. It seems somewhat straightforward in most cases (actually in all the cases I've seen). Then there was the term test, it was way better than I thot it would be, given that the first assignment was tough. And thankfully it turned out better than my advanced calculus quiz earlier last week. I think the only "surprise" is each question was worth 8 marks, instead of 5 marks as in the case of the past tests. Makes no difference tho since every question is worth a third of the total mark. The first question was the toughest for me, even tho it was more straightforward than the last. The solution to the last hit me less than five minutes to the end of the test. Thankfully I had written the base case and everything in the inductive step except the line that proves it. Overall the test was good and now I have to go work on the third problem set. Later daiz.

The number of points per question is a bit arbitrary. My idea was to guide your time management --- 50 minutes for 24 marks, so roughly 2 minutes a mark, or 16 minutes per question.
The approach you describe on your last question is exactly right: fill in everything you can fill in, so that if inspiration hits you in the last few minutes, you have a structure to insert it into.
