has there been any proof yet

has there been any proof yet

pretty sure theres been none so far, does that mean itll be even heavier on the proof for paper 3?

numerical methods defo havent, no proof i think as well
how does this exam board compare to others in terms of difficulty are most students here private or state

this is one of the more difficult ones because the questions are more applicable than theory. edexcel is known to be the easiest and there are more resources on edexcel maths

im external candidate, so ive just been studying from home without a college, not sure about others.

not sure about heavier but id say its highly likely to be on there
nothing on cosine and sine rule or circle stuff

what topics havent come up??
A list of topics that have not been covered much so far, if at all:
Inequality notation / modulus (functions) / quadratics
Transformations of functions
Simultaneous equations (Section A, linear & quadratic) to connect to using discriminant (b^2-4ac)
Factor theorem
Sine/Cosine rules (+ area of a triangle)
Differentiation from first principles (formula given just use it!)
Inverse functions
Binomial (General)
Arcs and Sectors
Small angle approximations (formula)
Chain and Quotient rule - maybe connected rates of change
Numerical Methods (anything, nothing so far)
Proof

so this might be a pretty vague question with no real answer. but from your guys experience with past papers, how likely is it for ocr to cover all topics in the syllabus? So in this paper 3, is it a pretty safe bet that numerical methods, chain/quotient rule and like differentiation via first principles will come up? or do sometimes they just decide not to? Is it a reasonable bet to just revise the topics that are yet to come up?

I’d say it’s pretty reasonable, yes
is this anyone elses last exam
praying for a factor theorem question fr

i feel like its probs physically impossible for every single topic to come up, they'll definitely usually miss a few of the obscure ones out. stuff like numerical methods which consistently comes up will almost definitely be in this paper, but differentiation from first principles has never really come up in any past papers that i can remember because its a bit more obscure.
does any1 have p3 2022 and ms pl
Hey, how did everyone find the exam?
