Is it possible to drop 1/2 mark or do the examiners take away a mark?
There's no such thing as half marks.

Great! Thank You.

Is it possible you could send me the exam paper questions?
Gill (at) Harkamal .co.uk

Also. Based on this, I have got 70/72. If I get say 60-65 on C2 to be safe. How much in stats would I need for an A?

Many thanks for the support.
5. Hi Mr M

2iii. I wrote a squeeze parallel to the x axis by scale factor 1/3

3iii. I got my method right but I got a calculation wrong and ended up with 5^3!

How many marks do you think I will lose?

2ii was a translation. I'm guessing squeeze is implying a stretch?
Mark scheme normally gives one mark for the identification (ie translation) and one mark for the direction and scale factor so you probably lost 1 mark there.

You would loose 1 mark from 3ii as you wouldn't get the accuracy mark.

Hope that helps. Best of luck.

10. Yes any C2?
11. For the last question I got 25, and I can't think where I went wrong. I got a right angled triangle with the base 5 and the length 10? Think the coordinates were (0,8) and (0,-2) on the ya axxis and centre (5,-2) then done 1/2 bh? Where did I go wrong. Will I have lost all 4 marks?
