It is 99% correct. For Q 10 part c, the QP says give your answer in the form , but the person has given it in the form

Is the question 10 (a) correct in the unofficial mark scheme. I have checked my solution but my graph of the equation y=x^2 (7-x) is not matching with the graph drawn in the mark scheme.

Yes, but the graph of bends again before intersecting the other one - that is not how it is meant to be. is , so it is the other way around and, if you put x and y equal to zero, you'll find where it crosses both the x axis and the y axis. What does your version look like? If it is an S shape, then it is wrong because is backwards.
7. arghhhh not this paper. This was pretty messed up. Especially the sequences question!

my college made me sit it as a mock. I only just scraped an A grade

Why on 10.c are you supposed to choose 4-2/3 and not 4+2/3?

Sorry, not sure if you know but you seemed to know the previous answer lol

Thanks
9. Ohhh sorry, because if you chose the 4+2/3, y would become negative

XD

From the sketch you did part a, you should see that the x co-ordinate of the point of intersection is less than 4. There is another point of intersection that is below the x-axis, and the problem with that is that it is below the x axis - the question says that both co-ordinates (x and y) are positive. Therefore, the x co-ordinate of the point of intersection the Q is asking for must be

Are you nuts, its exactly the same lol.

I agree - I don't think it should make any difference, but the question paper asks you to give it in that form.

I had this as a mock as well and I'm taking it a year early... help! I think I failed completely :/ checked the mark scheme and there are a lot of answers I got wrong...

I'm sorry but where exactly is this 'unofficial' markscheme. I'm being dumb, I know, but I just can't see it
