hey guys, just wondering should i be checking out old step papers or like the recent years to prep for the paper tomorrow?
Recent years. No doubt.

Recent years. No doubt.
thank you!
3. What would a an estimate for grade 2 for this year's STEP 1?

What would a an estimate for grade 2 for this year's STEP 1?
I reckon it'd be 65-ish.
5. Remind that the STEP I 2016 paper can be found here and the solutions thread here.
6. Damn. I tried for 4 fulls 2 partials (technically 3 partials as I began a question and promptly dropped it) but my 2 partials were rubbish and now it seems I screwed up part of one of the fulls. How much do you think this has cost me?
Spoiler:
Show

Q1) Copied Pn(x) down wrong for the final part. I did identify the correct values of n and x though.
Q2) Pretty sure this was correct.
Q3) Think this is correct, assuming my relative magnitudes of sin (-4), sin (-3),.. etc were correct.
Q4) I gave up after integrating the first time, thinking there had to be some neat trick I was not seeing.
Q7) I did only parts (i) (ii) (iii).
Q8) Correct.
Q10) I began hoping to make up for one of the disappointing partials in (4) and (7). I somehow got e = - intended answer. I did show that e < 1/3 (assuming the correct sign of e) but ran out of time.
7. Oh my word. Looking at the solutions to the STEP I thread... I didn't even get 1 question right.

Might as well give up on life now.

On a 100x easier note, anyone do the S2 MEI OCR Paper today?

18, 20, 20, 10, 10(?), 20, 13.

Looks like ~101. Question mark indicates completely uncertainty (i.e: no clue what I'm talking about)

I did slightly worse than you.

I didn't do the exam, but earlier today I had a go at Q 7. Pretty interesting, the first parts were easy, but (iv) was hard (I'm still pondering (b)). Definitely wouldn't have liked (iv) (a) under exam conditions, trying to write convincing proofs under pressure is not fun.

Yeah, I did what did you think of it?

I'm actually a little annoyed tbh, I found it incredibly easy. Which to me means any mistakes I made would be hugely amplified. I had 20 minutes spare to check my answers - something I've never had in an exam. Except C1 last year of course. But I always take my time. Tbf this is the first exam I took revision incredibly seriously.

There was nothing out of the ordinary apart from the question about the assumptions of spearmans test, but it was pretty easy to figure out.

Yeah I thought it was a pretty standard S2 paper, although wasn't a fan of the drawing a scatter diagram since the scales were awful. Yeah I actually saw that spearmans thing yesterday when going through some stuff thankfully, but it was only 1 mark anyways.

I finished with 35 mins spare which I never normally do in stats, at least I had plenty of time to check though.
13. My performance yesterday:
Q1 Full
Q2 Full
Q3 Assuming Full
Q8 Full
Q10 Full
Q13 Screwed it up big time. Maybe like 8 marks (just did the first part)

I keep hearing people mention the scales being awful - I didn't have any issues? One scale was jumps in 20 and the other jumps in 10 right? Maybe I missed something oops lol

what did you write for spearman's rank assumption?

Yeah thats exactly what I did just found it awkward since half the numbers were odd and so some you had to do a quarter of a square for. I can't imagine they'll be too precise with it as long as it's roughly correct though. What other modules are you doing?
17. Ok so I might as well put mine out there for some pro judging for step I:
Spoiler:

Q1- shouldve been all correct but a little messy when showing the n=4 case doesnt hold/didnt expand my powers of 7s at the end (although I dont think it specifically asked u to). 19ish?
Q2- Pretty sure that was a full after I stopped my self from being a fool and doing it wrong 20.
Q3- Being an idiot I wrote "arcsin ..." instead of interms of pi on my axes and may have (although cant remember) missed off the domain from 3 until pi on a couple of graphs, but all rest being correct and clearly labelled. 16/17?
Q4-Got the correct unsimplified form for f(x) but didnt rearrange or get geometrical interp. (Im guessing they just wanted to state it was a semicircle etc?) 14 ish? but not sure.
Q5- Full
Q6- Full except a little messy in finding one of the intersection points and may have given the wrong range of values for one of the constants/bad description at the beginning. 17/18?
Q7-Ran out of time so probably wont count
Q8- Completed all except the Fibonacci generating sequence as a rearranging error at the beginning of that part made my workings incorrect. Maybe 1 mark for trying correct method for that bit. How many marks would that part be worth?

Cheers. Given the roughness of these estimates and of our descriptions of the answers, we probably did quite similarly.

Yeah it is a nice question. But after going to town with the proofs in (i) (ii) and (iii) I didn't really have the energy or the time to bother with it so went in search of easier marks from the mechanics section.

what did you write for spearman's rank assumption?
It's that there's no assumption as it's done on ranks not actual values so there's no worry for the distribution of the actual data.

Oh I get what you mean, yeah lots of half way between one of the small squares - but that's pretty normal. I did M2 last year (got 91) and this year I'm doing D2, S2 and FP2. D2 went quite bad (i.e defo not an A*), I think S2 went really well, so I should just need around an A* in FP2 to get my A* in FM. You?

Just M2 and FP2, I'm unsure on how M2 went but should hopefully be 90+ still, so need fairly good A*'s in S2 and FP2 to secure my FM A*.
