Since it is a take home task and since it contributes so much to your SAC score, I would recommend you spend as much time as you can on it. Before you start, do a draft of what you're going to write. Flesh out your answers (I lost a mark for not doing this) as much as you can (you've got plenty of time), and check over your work afterwards. Good luck!

You got to take yours home? We can't...we spend every lesson for the next week working on it, and they give it to you in sections, so we can't change anything we did in the last lesson (to avoid cheating)...I'm soooo jealous of you!
I had to do the same 2 weeks ago. There's 3 parts and you have 45 minutes (1 period) for the first one, 45 minutes for the 2nd one and 90 minutes for the third one - which really takes 45 minutes, but the additional time is for catching up on previous sections, if still left undone.
The one I did was about some dude who lived off a beach, and wanted to build a fence on one side.....
Shouldn't be too hard. Good luck. :)

Did your teacher explicitly say that you really can't change anything you did in the last lesson? What my school does with this task is, give out in sections, yes, but we're allowed to go back and change things. We weren't allowed to take the question sheets or our bound books home..but most people commit the questions to memory and work them out at home to make life much easier.

lol i haven't even finished the chapters yet
Apparently my teacher is going to staple our other pages together so we can't edit them...I'm not quite sure how its going to work though.
ours is no-editing affair too, but i think we just get new questions each time and hand them back

LOL in that case he/she is going to have a hell of a job unstapling everything to mark :D maybe it would be nice to clarify whether or not you can go back and change things, because that will change your approach to the SAC.. hopefully you can, because it's really tough in these super-long SAC tasks if you're forced to finish things the first time round! Good luck. This is the "worst" one you'll have to deal with lol..

Good luck with it and everything.

So, I just found out that we are going to be allowed 8 pages double sided of notes into the SAC. What type of things do you recommend I should put on?
That's interesting...we were allowed to bring our entire bound books. Well, what I would do is write/type quite small..you should already have been given a general idea of what topics are being tested in this task, so maybe try to squeeze lots of examples in, of different types of questions so that you know how to tackle them if they come up in the SAC. And put in some key formulae too..but really, at the end of the day everyone works differently, so it's up to you to put whatever you feel you need on it :)

It was pretty close to what we had to expect in our SAC but yeah my school's one would be different to what you're going to be doing.
p.s. yes it was pretty scrunched up :P.

Uhm, this is what my teacher gave our class before the SACs.

"inclined at an angle of 10 degrees below the horizontal"
Are we supposed to be able to deal with angles in relation to gradients? My teacher said that isn't in the maths methods course. Moreover, the Cambridge book states: "This topic is not listed in the study design, but can be included for the understanding of other topics that are included." I hope you didn't have that in your SAC.

I know I'm being pedantic, but still, that's not right lol. If that happens then we should be able to use second derivatives and u-substitution.
From my understanding of methods, you can use the second derivative test to justify the nature of a stationary point, but u-substitution isn't required in methods, as the hardest integral they would give is like

hmm not quite...
second derivs and substitution method is beyond the level of the course.
whereas this angle/gradient conversion was part of the course in year 10 when you first learnt about linear relationships. [i'm pretty sure its in the VELS syllabus, if that's even the right authority :P ]
Post by: bucket on June 19, 2008, 07:12:17 pm
In fact, today I finished a section which had questions asking for velocity, and then asking for acceleration, and in the worked example these 'second derivatives' if I've understood it correctly were used. lol. I can scan it if you want to see.
I think that angle gradients are in the book somewhere as well :S.
