Agreed. I was thrown off by it having 10 questions (not like 7). Also the last question with simple harmonic motion ahrrr so mean of them. I never learnt any modelling / SHM as it wasn’t on the advance information
I completely messed up the differential equation, I’ll probs only get the marks for following through with my solution (so like 3 marks). Cos my initial AE was wrong. Rest of it was pretty straightforward, haven’t seen a polar question where they ask you to prove lines of symmetry before but it was ok in the end.
