Area = 369/10
9) line theough (0,C)
Asymptote at y= 5
equate and disciminant greater than 0
c<5-2sqrt(3) and c> 5+sqrt(3)

2. What the hell was that
3. Absolutely nothing on there that hasn't come up in a past paper before or was really easy

Yep lol. The area question last year was outrageously hard for C1. This year there was nothing. What q's did you find hard?

7. I got the same area for triangle. I made a silly mistake that I corrected but still used the wrong number :/ for the PQ distance question
8. What did people get for finding the question that gives you f'(x), (part a) an equation in the form of y+mx+c, and (part b) finding f(x)
9. The answer for 4 was 10316.
10. For the sum question i got 10,316 not 13016.
11. That was the hardest c1 paper I've ever done
12. Pretty sure the bike one is like 10,300 or around that, can't remember exactly what I got, maybe 10,316/7
13. Did anyone else get 123/20 or something for the area of a triangle (Q8)? What was everyone's coordinates for S and T?

People who did good know how difficult the exam was, people who found it easy are the ones who mis the questions thinking they did amazing. So, it's most likely this year was your worst paper attempt in these 3 years mate. 🙃😉
15. 10,316 for the bikes lads

OHHOHOOHO

I would punch the **** out of something rn, but iust told my parents that the exam "went well" so i can't, unless i want to look insane.
