Do all papers and i’d suggest write out the formula whilst doing the actual paper for e.g integration (if you want - depends on you total understanding) ....

then smash it!!

Did you think the structuring of C3 was a bit odd compared to past years? I thought it was.

This one was more shuffled, maybe thats just me 😂.

Can’t even estimate what UMS I had from C3.
Felt so prepared for it. I doubt C4 will be any better than todays

Yeah walked in confident af after doing C34 IAL and the recent past papers and hovering around A* boundaries. Now I'll be lucky to make an A after seeing the mark scheme...

Was really hoping to get A*. Now I'll have to get 100 in C4 which I highly doubt is possible.

I thought I wasn't very prepared for C3 but I wasn't worried coz if I thought it would be ****, then I'd deserve it. However, saying that, I found the paper decent and I was chill af while/before/after it ( i meditated beforehand which I 120% recommend). I only think I did fine because of the unofficial mark scheme and my instincts.

For C4, as long as the Vectors and Integrations are fine, the rest is easy to understand and practice.

No but srsly im gonna tell my bleepin mate to fix his snot out. That **** was disturbing af.

For question 'b' I got 4ln3 as an answer, but I can't do the second question. Which solomon worksheet are these questions from?

For c could you take out the 2 on the denominator and then it's x^2 -4 which is the difference of 2 squares so factorise and do partial fractions and then intergrate

In C4 will they only ask for the volume of revolution of 2pi and 360 degrees or can it be like 150 degrees?
