Wow! Well done! It was a few years back I think... The course costs are 3.2k? See I'm going to be hit by the increase in fees. Plus accommodation - I've really got to think about my financial position. It wasnt integrating factors was it? I was fine with seperable odes, constant coefficient second order (the one where you guess e^lamda*t) but integrating factors i must recap, also what did they ask about linear algebra? I dont learn the theory of linear algebra anymore, I just get matlab to do it for me when need be... why would they ask easy questions given the course materials looks pretty dam difficult? What options did you choose and did they ask any personal questions in the interview? (Like name 5 things you can do with a kettle?) sorry for 21s lol its just taken me a while to find someone who is doing this course, and given they only take 10 people on a year for it!
