How did everyone find it?


The difference between this paper and M1 last week is like night and day in terms of difficulty
kinda rough to be honest, although we started later than 1:00 pm and finished earlier that 2:30 so I ran out of time.

It was so terrible

that was a difficult paper I thought in comparison to last year's paper.
Especially that last question, that was horrible

Ive done so many past papers and got As and Bs and im certain i got an E on this😔

This paper was beautiful, I loved it x

pretty nice paper tbh.

How did people find the last question ? X

what did people get for the value of k- i seem to remember 0.048 or there abouts

think it was 4ln2-1

was that the one with the 2 overlapping curves?
If so i didn't get to finish that one but I was pretty sure it was just integrating with the necessary x limits and taking the result away from a rectangle.
I think it could've been ok had I not have run out of time.

Copy and paste of my answers from another thread- not sure how correct they are, any thoughs?

Q1 ii) Got -6.
Q2) One was even, one was neither, one was odd & one was periodic with period 180 degrees. -Not sure on this question.
Q3) Can't remember?
Q4i) 25% after 2 half lives.
Q4ii)k=0.0048 (or 0.048, can't remeber)
Q5) Something like (0.544,1.519)
Q6I)5pi/6
Q7) Had to facotrise and see it was n(n-1)(n-2). So one was a multiple 2 and one was a multiple of 3 so it was divisible by6.
Q8iii) Had to work out the trapezium and minus the integral. I remember it being 0.101, but you ahd to give it in exact form which I can't remember.
Q9i) It was a stretch s.f 2 on y and a translation by vector (2,0) I think.
ii) One was (3,0), the other was (4,ln(4))
iii) Answer was 1.77 I think, exact form was something like 4ln(2) -1.

I think question 6i) was 5pi/6

How did people do the very last question with the area of the two lnx curves

I got 4ln2-3 for that?

I think I got all of these but 5pi/6 for 6
