In which I waste time by cataloging the time I have not wasted and analysing this with respect to expected productivity and psychology. Sorry about the length, I have been posting a bit recently...

Resolution: I shall not rewrite my revision timetable. Too often.

Much of my revision has involved making notes, on the principle that writing things down gets it into the skull, and I can keep track of where I am. I have been trying to only make notes once I understand things rather than unproductively copying things. Here, ordered by date of first exam, are the numbers of sides of A4 paper used in my brief notes:

• Computational Complexity: 4
• Communication and Concurrency: 2.5
• Computer Algebra: 3.5
• Formal Programming Language Semantics: 1
• Computer Security: 2.5
• Computer Graphics: 15

Two things are obvious here. Firstly, there are too many Computer Science modules with "Computer" in the title. Secondly, there's an obvious variation going on there. But why? Here are some possible explainations:

1. Courses differ in volume of content and difficulty of material
2. My perception of relative volumes of content differs
3. My ability differs
4. I have covered material during the year to differing degrees
5. I prefer to revise particular subjects
6. I'm complacent about some subjects

Now, there is probably an element of all of these. I'm convinced that some courses are just easier, but there's a judgement/abilty call that's hard to make. And oddly enough, I hadn't covered Graphics much (basically what I had to know to draw a teapot, hence in-depth notes, but I genuinely think that would be hard to summarise breifly without just giving a "topics covered" list. Perhaps due to range of topics.

Interestingly, I also didn't bother with many security lectures, preferring to do other course/project work, but I haven't made as many notes. Is this course slower for wide audience appeal, or am I more apt? I have certainly come across some concepts before.
