Exam 1 Thoughts

[kido_1]

Well if you get 38/40 or 39/40 and you get 78-80/80 (depending on how hard Exam 2 is) you could still get a 50 if you SACs are good.

Remember, this years Exam 1 was much harder than last years.

that word "could" is a rela pain in the ass. Dammit i wish ym school had let me do a 6 th subject. Bastards!

lol

Calm down, it will be all right. No one that I have talked to so far is going to get a 40. Most smart ppl make a mistake here or there. I know for myself I mucked up that (A' B) question and so lost one mark. (39/40)

Silly mistakes= Gay way to lose marks.

prolly full marks on exam 2 for 50 i reckn..methods is heaps competitive...
i think im looking at 39/40 hopefully.....

I reckon you can still get a 50 with a 39/40 in Exam 1, if you kill exam 2.

thansk for the replies. O well best of luck for your exams too

hey i'm a newbie here =] anyway, i thought the exam wasn't that hard, but i made one dumb mistake, in 8b) - didn't cancel out the pi properly  :x  i agree, i hate silly mistakes so much! one question...would it be considered 'wrong' if i wrote a '+c' at the end of my antiderivative in Q7?

What was the question? Did it say find "an antiderivative" or find "the antiderivative," or was it *gasp* a definite integral (in which case a +C definitely would be wrong!).

don't think so cause that would still be "an" anti derivative

Edit: wait actually thats a family of derivatives.

[Collin Li]

With "an antiderivative," I believe they want you to explicitly choose a value of C. For the purposes of staying awake, I prefer to make my C = 1. People tend to choose C = 0, but it gets you in the inconsistent habit of forgetting the +C altogether sometimes, I reckon.

[bilgia]

i cant remember whether it was needed, but i put the +C...
i dont think it asked for  "an antiderivative" but just a general one...

[hifer]

They asked for "AN antiderivative" I'm sure coz i looked at it carefully and even underlined the AN to remind myself not to put the +c haha..

[bilgia]

o shit that sets me back 1 mark...dayum!

[JL_91]

maybe they'll be nice and give us the mark anyway   coz remember, they were nice about ppl forgetting to put 'dx' on the end of integrals etc. last year

[bilgia]

my teacher was saying they can take half marks off, but if theyre left with a non integer score, like 39.5 they would make it 39. so now i should hope that by that logic, my minor error with reading pr(x>2) as pr (x>=2) should get 1.5/2 and my other error with plus C warrants another half mark...so 1.5/2...leaving me still with 39/40 hehe LOL
