I hope this paper does not end up requiring a "Hitler reacts" video. that'd be unfortunate, for us.

If you've done C3/4 you shouldn't be worried about C2 at all. Every year people complain about how their paper was the most difficult ever. C2 is a standard paper and you should be able to smash it if you've done c3/4

Totally agree with you.

There will always be people who will complain regardless. Edexcel obviously every year is going to bring in some 2-3 new sort of questions which will discriminate amongst the students and only the 'top tier' can manage to successfully do em.

If you're well prepared, you'll smash it. Anyhow best of luck for the exam to whoever is appearing for C2 / C12 today!

Do we need to know about sigma notation?

yes we do,
however, it is calculated using
Sn = a(r^n - 1) / r - 1

or

Sn = a(1 - r^n) / 1 - r

Isn't that the sum of n terms formula? How do you deduce the common ratio and first term?

Honestly I think every single paper gets a Hitler reacts video! I find them rather funny, it softens the blow knowing other people hated the paper as well.
