What are the edexcel A/A* topics for non calc and calc papers? I know the function of x graphs like to come up on non calc, which I like because I'm good at them Any others? I've completley forgotten, hah. Thanks.

I'm not sure, but for the non-calc it's probably a good idea to know about the rules for indeces, Pythagoras' Theorem, circle theorems (oh how I hate them!), simultaneous equations, finding the equation of a line, transformations (inc. enlargement), bearings, quadratic equations (ALWAYS come up) and those tables where you have to say whether something like "xy + yz + xz" is a volume, area or length. Also have a good knowledge of basic numeracy e.g. percentages, decimals, fractions, surds, rational numbers, prime numbers, LCFs and HCMs etc. You'll also need to know some of the stuff you need for Statistics GCSE i.e. designing a survey, probability, histograms and (possibly, although I might be getting them mixed up) the capture/recapture method. For the calculator you'll most likely need to know trigonometry, the sine/cosine rule, finding the volume/area/density of shapes such as cones/prisms, as well as a lot of the things you need to know for the non-calc. That's all I can think of right now! It looks like a lot, but once you know it and do a few past papers it all clicks into place

Yeah, I should think that is about right. Why don't you check your specification? In general,

Non calc:
- Surds
- Irrational & rational numbers
- Quadratic equations (formula, completing the square)
- Volumes (eg working out the vol of a sphere inside a cube, or something)
- Bearings
- Vectors
- Simultaenous equations
- Sim. equations involving a quadratic

Calc:
- Trignometry
- Sine rule
- Cosine rule
- Pythagoras
- Circle theorems
- Growth & decay
- Trial & error
- Percentages

And other stuff....

Those topics can be B/A grades as well, it's just what they are demanding that makes them A* - I would say know trignometry inside out and the graphs, algebra you should be good at, there is bound to be a quadratic equation in the exams.

Thanks guys
I need to work on vectors.. argg.. how I hate them! I've revised circle theorems today *feels proud of self*
I also take GCSE Stats (but id be lucky to get a b, we only do it for an hour a week!) so im fine on all that stuff!

I have been entered for GCSE Statistics and we haven't had any lessons on it. Consider yourself lucky

My school has replaced all our maths lessons with statistics,(since january) so we have to go to extra lessons after school if you are doing higher maths.

vectors and trig graphs
what do the trig graph questions involve? i've totally forgotten, i had a sheet somewhere which i've lost... i remember drawing the table and plotting it, and reading off values or something? i know quite alot of symmetry was involved, as well...

For GCSE, I think you are required to draw graphs of the sine, cosine and tangent (maybe by using a table of values but you should probably know it anyway). Also, they may ask you some questions on their transformation: eg, if f(x)=sinx, they may ask you to draw what f(x)=2sinx looks like. Judging from past papers though, it doesn't come up that often.

you should know the general shape of sinx cosx and tanx
i.e. sinx goes through the origin, cosx goes through (0,1), tanx has an asymptote every 90 degrees

you should also know the basic transformations
i.e. sinx+1 moves up by 1, sin(x+1) moves left by 1, 2sinx is stretched vertically, sin2x is compressed horizontally, sin0.5x is stretched horizontally

you shouldn't need to make a table of points etc. you can just draw it from the basic shape, e.g. sinx goes through (0,0) (90,1) (180,0) etc.

I'd like to offer a comforting word to anyone doing GCSE Maths this year, which is that last years paper was notoriously difficult, therefore I'm willing to be they'll make this years slightly easier.

I remember that last year the final question on the Edexcel Mathematics paper was a simultaneous equation needing to be solved via the substituition method. This warranted 10 marks.

Lol, maybe the paper wasn't so hard then. :rolleyes:
