Just 6.


would you be able to explain the females at the gym please?
What is each mark for on the journey to France question. (E.G. One mark for the formula....)?????
For 22a) If i got 9x^6y^12 would I get 1 mark?

Not sure if I wrote 9 or 27 :frown:
thanks for this, slightly worried for my mark but will now count from this what i see as right,

is F=(9c+160)/5 the same as the answer he got though?

That is the exact same, just his is simplified a step further, you would still get full marks.

Probably 2 marks for knowing/working out that 50 mph is approximately 80 km/hr.

1 mark for attempting to use Time = Distance / Speed

1 mark for the final answer

That's fine.

I did the journey one without converting anything because i didn't fully read the question, how many marks would i get for just that?

Also, did the rationalised denominator need to be fully simplified? I knew it could, but i left it as a fraction anyway.
for 12b would it be ok to write 9c+32/5 , and for 23b would i get marks even if i didnt simplify
I got 88 omg..I thought I did much worse. YAY!
I estimated to get 86/100.
really happy , but just in case, im gonna aim for full marks on the next paper.

I hope everyone gets what they want to.

if you thought this paper was hard, then don't worry because you got calculator.

Dropped a maximum of 6 marks so I'm extremely happy :biggrin:

Thanks for posting this.
What would you estimate is an A* percentage for both papers?

I estimate I got 76/100 (worst scenario). Most likely, I still got at least 1 mark for showing working in questions I got wrong. I definitely got linear scale factor. Broke down simultaneous equation all the way to getting y right and then inputting it to finding x (I was panicking). I definitely multiplied the mileage by 1.6.

I will have to try to get 80+ in the calc paper to get A*.

Thanks Mr M.

would 1/100 have been accepted for 17b
Downloaded the mock to do tomorrow, is there a mark scheme for it? thanks :biggrin:

Counted probably about 75 marks which is awful for me, i normally get in the 90s, the amount of silly mistakes is so annoying!! Really need to get 95+ on friday now, pressures on :s-smilie:
For part c of the Quadratic graph question, i drew the straight line of x=3 and wrote down the co-ordinates where it meets with parabola :frown:
