They'll have to be lenient with our answers, so don't worry about it.

Well I calculated x=√(11/3), so its between √(3) and 2, 1.7-2 should the the correctish range

What did you guys get for qn 3? Solving for z?

Thoughts on mark allocation for question 4 if I momentarily caught autism and said Pr(z<-2) = 1-0.025=0.975

Fingers crossed it will only cost me one mark with adequate working?

What did you guys get for qn 3? Solving for z?

z=1+-i and 3

Yeah, the volume is essentially the area under the arc cosine graph times by pi because you square f(X) and it's just the integration of arc cosine. I thought at first it was asking for the volume rotated by the arc cosine graph and had a bit of a pickle.

Do you remember what you got for this question? I had two answers, 2pi^2 and 2pi^2-2pi, depending on what I chose for the terminals. I left it as the former one, between -2 and 2

Oh damn, I just remembered. I messed up Q.6, i gave the domain that would have been for a one to one sin function instead of arcsin...

Exactly how I felt, exam didnt feel super hard but I was just thrown by it

Is a 25-30 still possible if I end up getting like 15/40 on this one? Generally do better on exam 2 so say 45/80? Ranked ~15/40 in an average cohort.

Hey man, I know you did spesh at decv. Neale Woods or Georgia Gourous? Don’t worry too much about exam 1. It is done and dusted. For exam 2 l, just aim to do your best. It shouldn’t be hard if you got 17/20 for the multichoice questions at the exam seminar.

So annoyed, for the last question I originally didn’t it from -2 to 0 and then with 30 seconds to go realised it should have been 2 rather than 0, changed up all the answers and got 2pi^2 after crossing out the -2 that I had from my original answer which was wrong, I had it written as pi(2pi-2) and crossed out the -2 but never actually expanded out the pi... any chances of still full marking that question or would they take away a mark for not expanding?

For the second last question on the displacement of the particle after 10 seconds, was the answer suppose to be in vector form. Will I loose all 3 marks if I didn't give my answer in vector form?

[shiba woof woof]

i realised that the terminals from the last question were meant to be -2 to 2 just now...  how much marks will i lose from it if i did everything right except the terminals?

Is it still possible to get 45+ if you get an A for Exam 1. I stuffed up two questions on exam 1

[MG226]

Was anyone else as *intelligent* as me and say the probability was 0.05 instead of 0.025 

[tigerlily28]

Has anybody posted up solutions yet?

Can u still get above 45 if u stuffed up exam 1 (like lost around 3 marks) but aced exam 2??

[Kendog]

is it possible to get a 30 ss if i got 17/40 minimum on exam 1?

[tigerlily28]

Can u still get above 45 if u stuffed up exam 1 (like lost around 3 marks) but aced exam 2??

I stuffed up too. Lost around at least 3-4 marks....... What would be the cut-off mark for A+? Can I still get above 45
