Q1-14 were normal but Q16 and end of Q15 were hard

hoping for 88-93 raw

How does one find out one's raw mark? Does it come with the scaled mark/contribution thing in mid December ?

Someone correct me if I'm wrong, but I think we can buy our raw marks report?

Was a pretty hard exam (way way harder than 2017). Got all of the last polynomials question out (might lose 1 on the explanation), but screwed up the math induction =.= because i misread it oops. And also didn't do the triangle thing or the very last part of q15. Hoping for close to 90 raw. What would that scale to?

Does anyone know where solutions will be posted when they come out?

Terry Lee usually does them very fast, but his website doesn't exist anymore for some reason. Anyone know why?
Otherwise, I think the BOS admins do one, but this may take a day or two since they take extra care in providing proper solutions.

I believe Q8 is B instead of D

Also for the volumes Q in 13a they forgot to multiply the height by 2. Should be 2y not y

12a) there should not be a pi

N&S clearly just wanted to be the first to publish it, very unpolished set of solutions but it'll make do for now.

also for 12a they went from x to x^2 incorrectly. There should be a plus in front of the y^4 not a minus.
