For the area of the graph since between 0-4 was below the x axis you minus it? To get 162 that's what my text book says
No,the area is always positive, you got negative because the area is under the x axis, but you have to change back to positive, so it has to be 194+32=226
8. Dear god, please make s1 easyy

How did you do the log? How many marks was it? Completely messed up
From memory I think it was 7,

The method was pretty similar to other log questions, I can't remember the numbers used, although I do remember you had to may -2logy = logy^-2

the answers i got were y = 1/3 and y = 3/2, again off the top of my head.
11. It was a harder than average (clearly) and also more difficult than last year's C2 (which I did) as it required more thinking and time per question. TBH I expected it to be worse knowing that the exams are deliberately made more difficult each year, presumably because A levels will be changed. For grade boundaries I predict it will be very similar to last year's, so about 59 for an A, 52 for B, 45 for C and so on.

i got y=0.5x + 14/2
i think
It stated in the question write it as ax+by+c=0 where a,b,c are integers so you forgot to times it by 2 buddy
15. Guys if you think you've got it bad I've got to go and do a history exam in an hour after failing this lollllllllllllllllllz then chem on Friday and then i'll be heading to the crematorium if anyone wants to join

For one of the questions i went back and changed it because my marking was wrong, it was one of the easy questions i think the equation of the circle... at first i got something like 2x-y-6=0 or something then i went back and got a 3 as a coefficient and something like 34 as the single number!!
If my first answer was correct and i just wrote over it will i lose the marks?!!
17. Goodbye Cambridge.
18. Can someone kindly help me please? I need to see the C2 paper (or the mark scheme) please. Any links? Much appreciated.
