[stupidpersonlol]

okay so i am not getting a band 6 but what is the probability of someone doing well in 3u and 4u when they fucked the 2u exam lol especially all the stats questions. im losing hope in my maths skills but its too late to redo 2u && i also go to one of the decent selective schools and many said they found it okay im so deceased

WOAH AT LEAST U CAN DO IT NEXT YEAR...

The answer posted for Q23 is wrong, too. The derivative of is (as the solutions state) only if . The derivative is actually .

I was gonna say??? question infers that it is a positive constant but we cannot assume that the positive constant is e

lol nope, i practice math like a bastard

feel like my actual mark would be slightly lower

Yes, that's my impression, though it strikes me more as challenging than unreasonable.

Sir, can you check question 33? is that right? Aren't they independent events? So shouldn't it just be calculating the z score of z=(130-100)/(15)?

I almost left half the paper empty, probably got like 30% tbh

Q10 is wrong

Q21 has an incorrect turning point

Q22b is slightly flawed but almost correct

Q23 has been differentiated incorrectly and made the assumption that b = e, which is wrong

Q27d is debatable

those r the ones that are wrong as far as I'm concerned but everything else looks 100% all g
