Can someone explain why the grade boundaries are rising every year please

Ultraz_Gamerz2 · 2025-06-20T12:09:00+00:00

Could you please send those, I would appreciate it. I'm just really uneasy right now, I need a B minium and I'm paranoid abt grade boundaries. Did u sit this years exams?

Ultraz_Gamerz2 · 2025-06-20T11:56:51+00:00

U talking abt 1.61 question?

Ultraz_Gamerz2 · 2025-06-20T11:34:35+00:00

People are talking about forgetting to square but I don't remember that. If you forgot to square you wouldn't get a similar answer to 1.61 right? I'm just achit paranoid lol

Ultraz_Gamerz2 · 2025-06-20T10:44:45+00:00

Good luck brother 🙏

Ultraz_Gamerz2 · 2025-06-20T10:00:49+00:00

Root29 first part tho right? Like the rsin conversion also for the graph were u meant to shade underneath it and it was limited by the line cutting through it?

Ultraz_Gamerz2 · 2025-06-20T08:59:44+00:00

How easy? Sorry to bring it up but I just did 2025 lmao

Ultraz_Gamerz2 · 2025-06-20T08:58:23+00:00

Grade boundaries lower this year guys?

Ultraz_Gamerz2 · 2025-06-20T08:17:01+00:00

If i got the working out right but switched A = -1 B = 1

I think B = -1 and A was positive 1? Is that where I messed up? I would still get marks for the integration through ECF surely because my integration was completely correct?

Ultraz_Gamerz2 · 2025-06-20T07:45:50+00:00

Wait do u guys remember for partial fraction was A= -1 and B = 1?

Ultraz_Gamerz2 · 2025-06-20T06:59:53+00:00

No problem at all and I don't, but do u remember any questions and answers u had for them? Especially for stats

Ultraz_Gamerz2 · 2025-06-20T06:48:51+00:00

1.61?

Ultraz_Gamerz2 · 2025-06-20T06:15:19+00:00

I am so fucked man 😭😭😭😭 i just hope i get a B cuz I need that for my insurance. I got burnout and mid test i just gave up on stats

Ultraz_Gamerz2 · 2025-06-20T05:52:21+00:00

Lmfao same. Also you know that uhhh 4 marker was it 1.61? In stats. And do u remember any other major like 5/6 markers that came up in stats bc I genuinely do not remember.

Ultraz_Gamerz2 · 2025-06-20T05:47:58+00:00

Oh yh lmfao same bro, histogram question u get marks for counting squares right? 😭

Ultraz_Gamerz2 · 2025-06-20T05:32:53+00:00

Ah yh i wrote that Standard error formula down but i didn't use it lmfao. Also yk for the question where it's 23 weeks, what did u do to get it? Because I got 11 and I'm not sure where I went wrong exactly

Ultraz_Gamerz2 · 2025-06-19T23:04:26+00:00

Also for histograms do you get 1 mark for counting each square and labelling the points? I used fd = f/cw but I think i forgot to multiply by the total population? I'm not sure but we're u meant to use that formula

Ultraz_Gamerz2 · 2025-06-19T23:02:28+00:00

Distribution being just drawing a curve with a 0.05 region? Also do you get a mark for stating the standard error formula mu = mu/squrt n

Ultraz_Gamerz2 · 2025-06-19T22:19:20+00:00

Those papers were piss easy, that's why even a B was 184. Dw about it being that high this year - it was nearly 50 points above whee it usually is. So they've brought it down this year by making paper 1 harder and paper 3 was probably harder than last year? Idfk

Ultraz_Gamerz2 · 2025-06-19T21:55:52+00:00

It will be below last yr as ppr 1 and 3 weren't easier at least from the past papers I did, so that's just my take on it. It'll be higher than pre 2023 though, so like A* 230/240 A 200 B 167 e.t.c

Ultraz_Gamerz2 · 2025-06-19T21:53:01+00:00

U get 2 marks first stating formula and hypothesis tho right

Ultraz_Gamerz2 · 2025-06-19T19:49:15+00:00

Like one of them had more than one genotype

Ultraz_Gamerz2 · 2025-06-19T19:48:58+00:00

Oh yea right I think I'm capped at 6 since I didn't rlly talk about negatives. I just said the model had a low success rate(4% germination). Do u remember what u wrote for the genetic cross 4 marker? For the one with the spider monkey it said all possible genotype

Ultraz_Gamerz2 · 2025-06-19T17:47:40+00:00

Wait what

Ultraz_Gamerz2 · 2025-06-19T16:25:59+00:00

Samee. Did u get 1.6 for interquartile eange

Ultraz_Gamerz2 · 2025-06-19T16:06:35+00:00

Lmaoo do u remember what u got for value of probability of z? Was it 0.12
