I don’t know what I was thinking but for question 6, I left the answer at -15/9pi cms-1 instead of simplifying it! Would I lose the final mark?

generally you are required to simplify your answer so you will lose a mark.

What’s the general consensus about the grade boundaries? Higher or lower compared to last year? From looking at the solutions, I seemed to have lost around 10 marks on silly mistakes (extremely gutted as I got an A1 in the prelim), and am now looking at around 71/72 marks overall, so very borderline!

Thanks - this wasn't in the course when I did it so I was using general knowledge rather than gcd

I did the exact same thing😂 We should loose a mark but if it’s a common error they might let it slide, e.g. prior simplification in the first step, idk no clue!
