Hello everyone I was wondering what sort of revision techniques is every doing , I am guessing watching hegarty maths and past papers?? What did everyone get on unit 1 and unit 2 and aiming for ???
Good luck to everyone

I received a B for Unit 1 and a C for Unit 2. Mainly due to my pathetic levels of unorganised revision. I feel slightly more prepared this time. Once my Unit 2 resit and Unit 3 are out of the way, I'll probably cram a load of revision for Unit 1, and after studying algebra and trigonometry Unit 1 should feel like a stroll in the park. I'd be happy with a B overall for my GCSE.

I used to want an A*, which I still do, but I've got to be realistic. I don't really understand graphs of quadratic functions, pretty much anything graph-based has me confused, so I doubt I'll get higher than a B overall.

I dont get quadratic graphs at all. Also i dont know how to work out centre of enlargement/rotation.

Can anyone help and explain this question?

: The base of a pyramid is a square of side 10 cm. the total surface area of the pyramid is 300cm2. calculate its volume.

some how the answer is 288.7 but i don't understand why?

http://math.about.com/od/formulas/ss...eareavol_5.htm

Have a look at this webpage. It shows the formulas for calculating Surface Area and Volume.

1st - you will need to calculate the slant height (s) by putting the known information into the formula and solving it to find s.

300=2 x 10 x s +10^2
300=20s + 100
200=20s
s=10

2nd - you have to calculate the vertical height using pythagoras.

h^2 = 10^2 - 5^2
h = root(75)

3rd - you have to use the volume formula

V = 1/3 x 10^2 x root(75)
V = 288.7

Hope it helped I hope the exam will be relatively straight forward... Good Luck

Huzzah! I've finally mastered SOC CAH TOA. I've covered plenty of topics today thanks to Hegarty. I still need to revise some Unit 2, graphs and Sine and Cosine rule. I feel a lot more hopeful about this exam than I did a few days ago.

[BartoBarto]

Looking at that question really confused me aha. Back to the drawing-board I feel..

For the Sine and Cosine Rule, you are only given one formula in the exam, so make sure you are happy with converting them into the other forms; that is the first skill to master.

The Cosine rule is used when the angle is 'cosy'- this is how I've been taught anyway. Basically, if you have 3 sides or 2 sides with an angle in between; use Cosine.
Then, I just go with "Anything else must be Sine" and it's worked everytime. Failing that, use the Sine rule when you have a pair (after labelling the sides and angles) and go from there.

It doesn't sound that good on paper (or screen in this case) but, it works for some. Try it and see.

I hope I helped, a little.

has anyone else seen them questions where it is like 'estimate the height of this man in metres'? then estimate the height of the giaraffe in feet
they are the most stupid things ever, has anybody else been given past papers with them on?haha
yeah the papers are really hard i got 78% which was alright then like 62% which is shocking haha i need a high a* which just isn't going to happen

No I haven't seen these? Are they available online?

just wondering what's the volume of a square based pyriamid? im doing practice questions and i need to work out the volume of a frustrm thankyou

Thanks a lot for replying I got an A in unit 1 and and A* in unit 2, teachers have strong feeling that for this paper 63/80 will be an A* and 46/80 will be an A. I need 58% to get an A based on what I have and 78% for A*, but some people in my class need only 58% for A* . Anyway once again thanks, good luck and take care

That doesn't seem logical though. 46/60 is 57% while 63/80 is 78%! I'd find it odd if they had a 21% A boundary. I think the A* would be a bit lower maybe like 59 or 60

[lisa96]

i hate this exam so much. I got a C in both unit 1 and unit 2. i really want to get a B overall but that means i need to get at least an A in this exam which is impossible for me cause this is like the hardest exam

Sorry I may be wrong I was just predicting that based on what my teachers said and few other people on TSR. I know what I need but yeah you right that doesn't seem logical now I think of that lol I know for the specimen it was 50 for an And 60 for A* even though specimen is not an actual official paper, I think that seems more realistic grade boundaries. Anyway if I may ask what grades did you get in UNit 1 and 2 ? And what you aiming for ? ( thanks for replying )

[chelseafan]

Can someone please post a summary of what we need to know for this exam.

Cheers.

Sure, In Unit 1 I got 71/80 and in Unit 2 I got 93/100 which is a total of 164/180, so 91%. I'm hoping for an A* but I am finding this paper a little bit tough. There is a lot to learn, and now when I feel that I have covered most of it when I try papers I always get confused, especially with some of the Algebraic formula questions.

I'm hoping 60/80 would be enough so I'm gonna try and hit that. How about yourself?

Just to correct you, remember it is SOH not SOC, make sure you remember so you get it right in the exam. Good luck

Haha, sorry yes, that was a typo. Thanks. Good luck in your exam.

[SophieLisa96]

are you allowed tracing paper in the exam? my cpg exam papers say you can, but the aqa papers do not specifically say?

I got a B in Unit 1 and a B in unit 2, I need a B to get a B overall, or if I get an A* I get an A overall

Nice one that's good both of us averaging roughly the same, I think you got a little higher in unit 1 and I got little higher in unit 2. Same here hoping for an A* as well : hopefully we both get it, we need at least 60/80 on the paper for A* but looking at our grades possibly 63 will be confirmed and 48-50/80 should be A. True there are a lot more topics, some people said that the exam itself will be a little bit easier than papers as it is new syllabus and so need high grades to encourage schools to use their syllabus. The papers were not too bad : average, I hope AQA don't make it hard like physics unit 3: worst paper so far. anyway good luck and take care and I hope we both ace it, use bitesize and mymaths

[Young Hot Stalin]

I know the AQA have given official grade boundaries, however, is it possible once the papers are marked that they will adjust the boundaries, in particular making them higher? I don't know what would happen if they did

Anyone have any fail-proof ways of using the cosine rule to work out area? Or it is simply memorising?

Here are 2 papers I have located ( any chance of reps : new here so would benefit lol)

do you have the mark scheme for these??
