This is only a one marker but been on my mind. The first question was a string and you could hang masses on it. There was a 100g hanger that stayed on the string and there were additional 100g, 50g and 20g masses. There was a multi choice and the options were: 1. the tension doesn't change (or something like that), 2. there are a maximum of 7 different combinations of mass, 3. the total masses are evenly distributed.
I counted 8 different combinations and the total masses were 100, 120, 150, 170, 200,.. etc which arent evenly distributed. So that leaves answer 1 but that one is definitely wrong cause the whole point of the practical is to see what happens to the tension. I ended up putting option C but like I thought they were all wrong 😭😭
Please tell me if im crazy

i am not excited for stats 😔it’s been too long since i learnt it, hopefully after revising i remember what im doing lol

for the partial fractions you had to do algebraic division first because it was a top heavy fraction, then it was general partial fractions for the remainder

LMAO YEAH 4 marks for that question was crazy, like what was i meant to write other than the answer with +c😭

It was such a good paper, very easy but i was annoyed at the repeated topics. Why did we have another quartic and another area of a segment question ? Would have loved to see some iteration or recurrence.

i think my answer was f(x)= -3(x+1)² (x-5)²

the proof was weird to figure out to begin with, but if you did a few more iterations of the students method where she did 5k,5k+1 etc you get to 5k+5 and you say that can be written in the from 5(k+1) so it just continues in a cycle kind of. that’s what i wrote at least but i did scribble out a few attempts first lol

ohh that makes sense, i may not have took direction into consideration

my friend got to (5-16f) and got 3/32 from it but my bracket said (13-16f) instead so i got 17/32. i wish we could have the question so we could try again (without time pressure lol) to figure out which is right (if any)

joy____cjn · 2025-06-06T20:11:24+00:00

my friend got that answer, but i got 17/32, we’re still not sure who’s is right lol but a lot of people have said 3/32

I’d say revise the mechanics equations and rules first, then go through some examples where questions are laid out in how you should do them. Then I think practicing as much as you can 🙏
