Idk but I think this community most active during exams which is why I asked cuz later no one replies 🫡

OMLLL WE GOT BETWEEN A ROCK AND A HARD PLACEE😭😭

WTHH 💀💀💀 IT WAS OUT OF MY PREDICTIONS 😭😭

I CAN'T DO THIS ANYMOREEE 😭😭😭😭🙏🙏🙏🙏

IDKKK 😭😭😭

I HOPE THE GB IS LOW OR THEY MARK MY ANSWER LINEARLY 😭😭😭😭😭😭

was very hard compared to papers jan 24-jan 26, id expect around 60 for an A

Q1.

dont remember c

k=20.4

inverse was 1/10k-204 and then the changed c

Q2.

focus (5/2,0) diretrix x=-5/2

points where (35/2, 5 root 7) (35/2, -5 root 7)

Q3.

a+b=1/2 ap=3/2

a^3 + b^3 = -15/6 or divided by 4 i dont remember

32x^2 + 230x + 575 = 0

Q4. i dont remember

Q5.

proved within the intervals

the interval bisection was [5.05, 5.075]

f prime x = 1/10 -3/2 x^1/2 + 4x^-1/2 + 8x^-3/2

estimate for beta was i think 3.324 or something along those lines

Q6.

other root was 1-4i

z^2 - 2z + 17

factoriised form f(z)= (z^2 - 2z + 17)(3z-2)(4z+9)

A = - 5 B = 148 C = 359

argand diagram had points 1+4i 1-4i 2/3 and -9/4

Q7.

first was a strech of scale factor of 3 parralel to y axis

second was (0, -1) for top row and (-1, 0) bottom row

product was (0, -3) and bottom row (-1, 0)

last part was insane by the way, had to derive my own area of a hexagon which turned out to be wrong, so i think ill get 1-2 marks but the answer was 1.96

Q8.

indcution dont really know hot explain but f(k) was factorisable in f(k+1) with a 5(2 to the power of 2k)

Q9

first proof was explanatory

could not prove second, anyone did it? i plugged in point so got 1

last one was 10 got it wrong tho

How was the exam!!!!!, decent paper for me, very common questions from past paper, I saw the mcqs and some questions similar to 2023 Nov paper 2r which I practiced last night and other common 6 marks and 9markers...how it for you guys?

THE BESTT paper istgggg
Expecting maybe full ums?? Not sure but i feel i did correct

Am I the only one who is tooooo scared from that unit ? Bro the questions ain’t even from the syllabus 💔✌🏻

I found most of the questions very straightforward, about questions 7 to 8 it starts to get tricky and questions 9 is just "what the fuck"

THE ENTIRE QUESTION 9 ARE ALL UNKNOWNS THERE ISNT EVEN A REAL NUMBER TO DEAL WITH ITS JUST HARD PROOFS.

Anyways for the summation thing does something get sth like 280xxx ish? I forgot the number but that should be close.

How was it? What questikns cane up

0.0022 mol

0.0011 mol

0.011 mol

n=10

48.7% yield

another way was to heat until constant mass of crucible with mass, weigh crucible mass before after heat resistant gloves.. etc

seperating funnel, bromopropane was lower layer

m/z peaks CH3+ 15

and CH2OH 31 peak

alcohol, aldehyde

simple distillation, heat under reflux

also what would happen to the mixture??

brown fumes to identilfy bromine

rotten egg/pungent smell to identify iodine

Same, higher or lower?

I do non-R and we got 127 Hours, and though the school didn’t predict it, I did so I felt prepared. The transactional writing was good too, as I chose to write the letter on peer pressure, where I explained that it was all bad and disproved the counter argument. What do you guys think?

PLS list em

question discussions

am i the only that genunly couldn't answer shi or am i just under prepared,

its stessing me out everyone saying its easy

The last question tried to 🍇 us istg

That paper was sooo easy gbs gonna be high asf
