wtf was that paper
started out pretty reasonable then turned into absolute bullshitmaxxing
maths a level students come

if you found it easy then you are an absolute fucking genius. even the a* students found it difficult
yeah id like to know what "easy" means, I got 95/100 on my last mock and I think I might have barely broken ~80 on this one
I'm usually quite good at getting like 55% so if the boundaries are lower this year that's good for me I thought question 1-9 were free
To be honest I thought questions 7/9 were some of the most difficult mid-paper questions they've ever released, and then the last 4/5 questions were also more difficult than normal
Tbf my teachers held a maths revision thing right before and since I need a B I've been nonstop revising for the past 3 weeks so maybe I'm just more locked in than usual and the paper actually was really hard
Nah I'm going to open the envelope on results day and get a D atp if literally everyone else found it hard it's so cooked 😭
yeah the first few questions were somewhat reasonable except the circle one then you had the geometric series question, the proof question and the last differentiation question just to name a few
I got 2 for that one,
I flipped the "tan(a+b)" formula to get (1-tan^2x)/(2tanx)
then you expand the equation it gives you to get cotx - tanx which becomes (cos^2x - sin^2x)/(sinxcosx) -> (1-2sin^2x)/(sinxcosx)
you derive 1 + tan^2x = sec^2x, so you know that 1 - tan^2x = sec^2x - 2tan^2x
which becomes (1-2sin^2x)/(cos^2x)
therefore, cot2x is equal to (1-2sin^2x)/(cos^2x)(2tanx)
which is equal to (1-2sin^2x)(cosx)/(cos^2x)(sinx), so (1-2sin^2x)/(cosx)(2sinx)
which is exactly one half of the expansion above, so therefore k is 2
Geometric series one you're supposed to equal term4/term3 = term5/term4 to find theta=pi/6, then sub that into term4/term3 to get root6 as the ratio, then sub pi/6 into the third term and divide it by root6 twice to find term1/2, then add term1/2/3 together. Not a clue how you do part c) of the Algebraic integration one though, I got stuck in an infinite integration by parts loop
Unironically hardest paper I've ever seen, thought they accidentally gave me a Further paper or something. Don't think I did too badly, but objectively those questions are more difficult than all the past papers, so silver lining the grade boundaries should fall.
bruh I can’t it happened less than 5 hours ago, british exam boards release the exam paper publicly a year after it took place
