Calm down old boy, so far as I could see the only pokes were at Americans (always fair) and Comprehensives (often fair).
What you are doing sounds very similar to my further maths A level some time ago. I imagine you are doing more Newton Raphson, etc. than I did because that's a big player in computer analysis, and some stuff has been dropped off to balance the syllabus.
Now Imperial, well I could start on them, but probably only on principle because I'm a Southampton graduate....
