You 100% will don't worry im thinking around 58 for an A as student room is going to have people that want to do really well you can't judge it by this community getting 65+

However you need to obviously do the same with c2 and s1!

Thanks for the reassurance. I'm hoping S1 and C2 go better so I can get an A overall.

q1) a=(pie)r^2(x+y) when r>0 find r
the binomial: (3x-2)^4

q12: y=2x+k, 3x^2+12x+13
ii) complete the square and explain why the curve doesn't go below the x axis
iii) What is k when the line touches the minimum point of the curve.
9b) x^2 is an integer - x is an integer
3(b) (25/9)^-1/2
3(a) 10^0 or something

11i: 2 marks
11ii)
11iii) 6 marker
12i) 5 marks
12ii) 5 marks
12iii) 2 marks.

For question 12, part iii. Is k=5 , 100% correct. I got that bit but I didn't get part i (I used the discriminant but I forgot that the minus k attached onto the 3....)

for radius, i just put the radius it said in square root form. i didn't simplify it. I just put, squareroot125.
please tell me i wouldn't lose a mark for that trivial mistake.

wondering how many marks I'll have lost on question 10) c for not changing (x+1)(x+1)(x-6) to (x+1)^2(x-6)?
thanks for posting this also :smile:

could be wrong but I've seen in previous past paper mark schemes that they accept it unsimplified :smile:

(I did the same thing so fingers crossed!)

Wait what.. they penalise if you don't simplify? I put (x+1)(x+1)(x+6) and for the circles question the radius as root 125........
