i believe 8 is supposed to be C and 10 is D
hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
are you sure? it says 'at least one'. I thought multiplication is for when all of them are true. I added them together to get a as it is EITHER of those probabilities.

For the bearing question, if you did the bearing from A to C instead of C to A, would that be a straight 0/3? Can't believe I did that...

And also just for curiosity what would a raw mark of ~90 align to?
I did the same thing for bearing... anyone have an answer to this?

My predictions were correct, Q 15 will be the hardest section :)
considerably, i mean q 16 was just full of 'show' this and 'show' that and they just chucked in a simple integration question and a slightly harder simpsons rule and a 'bit' more complicated r value (1.01/1.003) for the deposit part

You get 0 since it was unnecessary to calculate that angle.

90 raw will align to 92-95 depending on the cohort's performance.

wow. i skipped part ii and iii - and im luck i did



I probably put D as well. just didn't recall properly
Are you sure that 10 is D? I thought it was A
P(at least 1) = 1 - P(No one wins) = 1 - (3/4 X 5/6 X 3/5) = 5/8
