Keep getting As on GCSE edexcel papers

hi, i want to do futher maths at A level, but i have done 6 past papers (equating to 3 full past GCSEs) and i have gotten As on all of them..

between 135-155/200.

I don't know what else to do that will help me get A* that i need, other than past papers, can anyone recommend a way?

thanks in advance..

What are you losing marks on?

Does a lack of knowledge ever cost you marks or are you sometimes unable to see how to answer a question?

Post some of the question you got wrong if you like.

Well, i lose a good 10 marks from stuff i don't know, and maybe a futher 5 from making mistakes such as not reading the question porperly e.g. putting a time such as 30mins and not a time of day which is asked for like 4:30pm.


i'll find the paper i got back today and link you in a second..

What about the rest of the missing marks?

question 18, i gave rotation 180 degrees about (0,0), the first 2 were correct but the last wrong, 2/3 marks...

23. 2 x pi x 5^2= 50pi WRONG????

24. i have no idea how to work that out..

also lost marks on 14. but i can learn that from the textbook..

You need to learn how rotations work



What question



That worries me - tree diagrams are a standard question



Very standard question

For 23 you did the area of a circle multiplied by 2 when it's the surface area of a hemipshere...

So find out how to work out the surface area of a sphere.
Divide that by two.
Work out the area of the circle at the bottom of the hemisphere.
Add them together!

i'm pretty sure though its (0,0) i have gotten rotation questions correctly before..

Did you draw the new shape

It certainly is not (0,0)

so (4 x pi x r^2)/2 + pi x r^2?

yes...

So why did you think it was (0,0)?

well its mapping P to R, i dont see how Q is relevant... there is 1 square between each at point 0,0..

What was the correct coordinate? :P
