That's sooo annoying!! But hopefully you'll get a couple marks anyway for showing full working


Yeah! The last question with the quadratics was good, I surprising managed that but the trig identities?!? What even, I only knew that tanx = cosx/sinx or something like that XD

Because the fraction was 60/100 it couldn't of been £4.95 as that's less than £13.75! I'm with u though I put £4.95


well if you cross multiplied so ( 100/13.75 x 60/x) then you would get £8.25 but i put down 4.95 anyway ugh lets all hope its 4.95 ahahahah get rekt

OH JAY, I COULDN'T HAVE SAID IT BETTER MYSELF.

The paper 1s that they had in the past years were OUR level and they were exams that we were able to do with some hard work and revision but now they give us this ...

I'm just so glad I'm not the only one


Mate don't worry. Near enough EVERYONE at my school was freaking out after paper 1. I am 100% positive that they will lower the grade boundaries.

Absolute piss take imo.

I hope so!


It did say the area was proportional to the price so thats why I squared it.

I don't see why its £8, I got £4,95

I'm confused as well. I got 4.95 as well and I don't understand why it would be £8

Did you find the volume of the large one then the small one then just took them away from one another?

havoc in twitter complaining abt paper 1 ahahaha:colonhash: mostly complains about the trig identity question which was tan^2x cos^2x.
The answer is sin^2x because you know that tanx = sinx/cosx so you just have to simplify the question

Wait is it exactly 5300 or is that just a rough estimate of what you think you put ?

I believe it's 5300 yes. Rounded to 2 sig figs

Do you think I would get the 2 marks?

I wrote sin^2x... That's all lol. I knew it had something to do with six/cosx though
Anyone got the paper? Did AH today and wanna see what all the fuss is about haha

Did the question ask you to round it to 2 sig figs ? If so I didn't do that :frown:

Basically Paper 1 was not bad until question 7 rolled along. After that things just got worse.

Paper 2 was honestly a piece of cake.
