i'm pretty bad at physics lol im hopeless

Yeah, they did give you three options: Remain stationary, turn clockwise, turn anticlockwise. I wrote anticlockwise at first, then I changed it to clockwise, and bull****ted about some imbalance of forces and centre of mass. I think I'm wrong, though.

Ohh! I wrote anticlockwise because the weights don't change. And for the reason I wrote that anticlockwise moment > clockwise moment. But Im not sure if Im right :/. Im confused! :s I guess we will just have to wait for the results to come out.
In the threads of xtremepapers.net also, everyone has complained about this physics paper. But there is this friend of mine who actually found it very easy and finished the paper with 20 mins to go! I still dont understand as she was the only one who found it soo easy!

Hey, what are you guys doing for Chemistry Extended??

Keep in mind though, people may think its easy but may not truly understand the difficulty of the question

did you guys get 2.6 days for the half life (last question)?

lol doing all the papers :P
i still have 03-11 november papers! i've done the rest..

I got that, except when I talked to my friends after, some of them said it was like 1.5 or something, since you had to minus the background radiation.

our whole class got 2.6 lol

I know! Most of us think the same but she seemed so sure about it! Anyways we'll have to wait for the results.

I think physics variant 1 was an incredibly hard paper! Most of it ended up being guesswork :/ did anyone get the question about why the water levels initially fell and then rose?

[Mule]

I put that water evaporates at first and then after the water expands but after researching on other sites its wrong. Apparently the answer is that the glass expands first which causes the level to go down and then the water expands afterwards (and by more.) I think thats a BS question tbh, because there's nothing like that it my book(although some people said it was in their book) and also I thought glass was supposed to not expand by much. I believe evaporation would be far more noticeable than glass expanding -.-...

oh right, I see! But yeah agreed, honestly never seen anything like that before nor learnt that. How are we supposed to know things like that? Ah. Also I found the thermal physics questions pretty challenging! Latent heat and specific heat capacity are supposed to be easy marks by just using the formula, but I was really confused with the question they brought :/

Hey, for the ones who do Chemistry http://www.xtremepapers.com/communit...yllabus.16647/
This has an attachment which contains a compiled revision of almost the whole portion of Chemistry. Check it out!

what... how... why. no. How can you be so sure that's the correct answer? Is there a mark scheme out or something?
I went on about pressure rising in hot water so it fell slightly or whatever, then the water expanded and rose.. i honestly can't remember it was all BS guessing.
How do you know that's the answer?

Are you sure that's the right answer? One of my really smart friends got 2.6 so i though it would be likely it was right. *sigh*

I'm not certain it's the right answer but it's what some other people have written, and one even quoted it out of a textbook.

But still, I don't see how we're expected to know that -.-

Paper 6 physics is really easy, but I have a little question on plotting graphs.
my values here are 0.22, 0.03, 0.04, and 0.05
I need to put these on the x-axis, and i have 60 squares, divided into 5. so every 10 squares i can put a number. But how do i include them all? do i have to start from 0? 0.22 is just too far off from the rest, so it ends up being a really small graph

anyone help, please? thanks.

btw, its question 1 (a) and (b) October/November 2010. variant 1. -0625/61

Oh cool, I did journeys end too. Which question did you do in the exam? Did you like the play ?

Yes I had that one aswell - Variant 1. So difficult!

Seriously... I went into these exams confident due to my grades on all tests we've done and on past papers coupled with my many hours of revision, and after this - especially chemistry practical, and physics paper 3 (i'm not sure about Biology) my confidence is shattered, I feel so depressed. It feels like all my work has been for nothing and everyone is going to be shocked and disappointed in me...

Same here, dude..same here. Chem 6 and Phy 3 have all but shattered me. Suddenly, it seems as if all those shiny A*s on all the tests have ceased to matter But we mustn't lose hope, I guess. I mean EVERYONE's papers went bad so it's not like CIE's gonna have no A*s this year..they'll HAVE to lower threshholds, won't they? And even if they don't 150/200 for Physics is still pretty get-able, even with the bitch of a paper.

lol i got it wrong anyway XD
i put anticlockwise then changed to stationary..
cuz the moment's still the same..idk lol
isnt the cosine theta thing still the same? XD

LOL I put it anticlockwise...then clockwise..and then (can you believe it!?) stationary. I thought of the same thing..that the moments should still be same (cuz wont the perpendicular distances be the same) but honestly, that question should never have been set in the first place!
