So I just fucked up my exam 1  I've been averaging 87% in sacs, if I do relatively well in exam 2 what are my chances of getting 35+?? So pissed rn

wasnt it either 5pi/6 or 11pi /6

Should be only 5pi/6 because that's the obtuse angle (150 degrees)
11pi/6 is a reflex angle (330 degrees) if calculated from the x-axis in an anti-clockwise direction

For the last question, part a
Were you required to write the whole thing out as an integral? I only did the differentiation but I realised it could be interpreted that you needed a final statement

[Gromekk]

I didn't, was 2 marks so didn't think i had to do anything else

Hey! Don't worry too much. I know a lot of people in my cohort found it to be a challenging exam (and I go to a selective school). Also, exam 1 is only worth 22% or smth (your SACs are worth more than this!), so you still have a really big chance tomorrow to get that 35+. I'm guessing a high A tomorrow should be enough? Good luck!

Okay so I have verified my answers with a friend who tutors, with 40/40 on exam 1 can I drop any marks on exam 2 and get a 50+ premiers?

Want to swing us your answers?

How did everyone approach question 7?? The question with line A and line B.

Well what do you think you got on exam 1? Exam 2 is worth way more than exam 1 by the way

(0.05 x 40/90) + (0.08 x 50/90)? something like that anyways

I'm also in the same exact boat as Jazzaa36. I've been average 86% for sacs, i have really messed up that exam, probably 29/40 to be honest. I was really hoping for a 37/40 as that was what I had been averaging in my practice exams. If I do smash it tomorrow, say 72/80? Is there still a chance of a 40 raw? Or is all over?

But in exam 1, scores are more tightly condensed at the higher end, meaning that every point you lose in exam 1 affects you more than every point you lose in exam 2.
