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

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

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)

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. 🙃😉
