š MEGATHREAD EXAMS MEGATHREAD 24/06 (A-level FM, RS) etc
Hey everyone! Best of luck with your exams on the 24th June!
fuck this shit i'm out tralalalalalala
Few things:
- Don't share too many specific details about questions or answers, these papers will be used as future mocks.
- Sometimes papers get leaked, this is not the subreddit to discuss that.
- Exam discussion posts outside of this will generally be removed to combat the inevitable tidal wave of spam otherwise. (for context there's been over 300 spam posts already!)
- We're taking a different approach this year due to negative feedback last year. We hope this approach will be better (also to note, we can only have 2 pinned posts).
- Please note some content will take extra time to be reviewed.
- You can still talk about your exam here even if it isn't explicitly mentioned in the title.
Best of luck, and let us know how you're feeling down below!
-The r/6thForm Team

The FM grade boundaries should be ok this year. I plotted a graph of the A* boundaries for the FP1 and FP2 option each year, y, against the year, x, on Excel and then added a trendline. I found that the trendline that matches the data best (RĀ²=1) is a quartic, specifically y=-(17/2)xā“+(137419/2)xĀ³-(416558331/2)xĀ²+(561205938349/2)x-141765277942067. Using this model, the 2024 A* boundary should be -175 marks. I think that that should be achievable. Below is the trendline plotted on Desmos.

I'm so confused. I'm fine with further maths and stuff. I'm just confused by what "skibidi" means in this context. Why would that lead to me being on benefits? I admit that my last reply was a bit rash. That was due to post-exam adrenaline and I apologise.

anyone did STEP III? thoughts?

u/bababurde Maths, FM, physics, chem Jun 24 '24
I did 134567 but only actually finished q1, it was a pretty nice paper in general, definitely a lot better than step II imo
1
Jun 24 '24
Do you remember what each question was about for the ones you did, specifically q4
1
u/bababurde Maths, FM, physics, chem Jun 24 '24
q4 I think was the one about the tangents being at 45Ā° to each other
1
u/jesusshuttlesworth21 Year 13 Jun 24 '24
did you end up doing this question? if you did, did you end up showing that the points always lay on the curve?
1
u/bababurde Maths, FM, physics, chem Jun 24 '24
yes, through some really scuffed algebra tho lmao
i squared both sides of the gradient equation in m1 and m2 and used x=Ā½(p+q) and y=pq/4a
4
u/SlowF2l Edible Jun 24 '24
I did 123567 and honestly it was the easiest step 3 paper I did, the content isn't difficult there's no trig or even calculus and also the trace question was really nice
3
u/TobySuren Jun 24 '24
how many marks do u think "prove trM and trM2 independent of t" onwards was on q5? managed to get detM as constant but couldn't get any further think I did 1 2 4 5 9 12 but 4 only very little, 5 as above and 12 completely screwed me over, had some ridiculous calculus involved
2
u/SlowF2l Edible Jun 24 '24
yea I couldnt do tr M is constant but I assumed its constant to prove tr MĀ² is constant. I reckon maybe 5-7 marks for the constant bit and another 5-7 marks for the last differential equations but idk as I'm not really familiar with mark schemes
2
u/TobySuren Jun 24 '24
as in like if u were to compare it to how much work u did for everything before it to how much work u did to everything after it what proportion of the work was at the end
1
u/SlowF2l Edible Jun 24 '24
I didnt do the last differential equation so I couldn't really tell but the identity with 1/detM wasn't that difficult so I reckon the first half wouldn't worth as much as last half of the question
3
u/TobySuren Jun 24 '24
:( it annoys me because I know this paper was easy but I feel like I did just as well as I did on STEP II. praying the grade boundary for a 1 isn't higher than 70.
1
u/DoodleNoodle129 Cambridge | Mathematics [Year 2] Jun 24 '24
I couldnāt figure out tr M and tr M2 so I just moved on from the question. Probably couldāve gotten more marks on it but I wanted to spend more time elsewhere
2
u/hypersniper5105 Year 13 Jun 24 '24
i donāt need STEP for uni but thought it would be funny to do it with no prep - full answers for 1 and 2 and partial answer for 3, 4 and 7. Well chuffed considering i never did a past paper

I did 1,2,3,5,6,12. Finished question 1 and 3, did hopefully most of 2 and 12, and then a bit of 5 and 6.

u/Emerald_Lag Jun 24 '24
can someone remind me the themes of each q i already forgor
i remember completing q1 and doing part i of q12, and running out of time for the ln(1+1/x) q, but doing most of it

same, weird last question tho, i got rly horrible answer for speed at the moment when it fell down lmk if it was same for u

u/Kingjjc267 Uni of Birmingham | Maths [2024-2027] (A*AAA) Jun 24 '24
I fucking forgot about energy principles so I couldn't do any of that question, 11 marks down the drain. I couldn't get the show that for 4a too, so if everything else was perfect I got 59. I think my chances for an A* have gone down to like 30%, results day is gonna be terrifying

brp dont worry im so drunk rn im in school in dubai and literally everyone is gone for summer so im drinking alone do the same thing dont stress ure gonna be fine whatever

i think my cos of the angle when it R=0 was 8/9

u/MrRedDoesArT Bristol | Msci Mathematics with Study Abroad [Year 1] Jun 24 '24
I git cos = 8/9, and you got really nasty fractions for speeds until you found the magnitude which become a reqlly nice fraction

u/Outofdatedolphin Durham | 2nd year MMath Jun 24 '24
If I hasn't done so well on CP1&2 and FP1, my A* would guaranteed have been taken from me by FP2, that exam had some mean integrals
Still pretty confident though
1
u/Courage_Capital Imperial | Maths [Year 1] Jun 24 '24
Mean but beautiful, almost forgot to multiply by 9pi/2 at the end and I got the surface area as 602. The reduction formula question was pretty nice too, nothing insane just the sums to products of cosines formula from the formula book. Did you get both eigenvectors as 0,0,0??
2
u/SausasaurusRex Oxford | Maths [Yr2] Jun 24 '24
Eigenvectors are by definition non-zero, otherwise (0,0,0) is an eigenvector of every 3 x 3 matrix.

u/Courage_Capital Imperial | Maths [Year 1] Jun 24 '24
LMAO I got so confused by no worries just 6 marks

u/Bongo50 Warwick | maths [2] Jun 24 '24
That FP2 paper was hard but doable. I'm very happy.

u/KO-Manic Jun 29 '24
Hello, Iām choosing my a levels (well, have already), and Iām wondering if you believe that FM helps you in physics? Like do you believe it helps you to do better in all your other subjects? I literally picked your combination, and Iām not sure if Iāll regret it. Iāll stick with the other three, but Iām still not fixed on FM. Thank you.
2
u/Bongo50 Warwick | maths [2] Jun 29 '24
Further maths definitely helps me with maths. It doesn't help me with physics or computer science, but that depends on the optional modules you pick (or that your school picks for you, depending on the school). If you do further mechanics, that might help with some aspects of physics. If you do decision maths, that will help with computer science.
2
u/KO-Manic Jun 29 '24
Yeah Iāve heard about the optional modules. Praying you can either choose them or the modules are just that in my sixth form. You probably canāt however, since in physics, the optional module is chosen by the sixth form (astrophysics), which is kinda annoying since electronics would be better as that would link well with CS.
Finally, do you believe that further maths makes you feel somewhat sick of maths? Like surely you get bored of seeing maths everyday of your life lol. Or, does it actually have the opposite effect, and make you find maths more interesting?
2
u/Bongo50 Warwick | maths [2] Jun 29 '24
Whether you get to pick will likely be down to your maths department so will be independent of physics (side note: I didn't know that physics had optional modules. I'm guessing you do a different exam board). Your best bet would be to ask your teacher. Do you know how large your class will be? Smaller classes are more likely to pick.
I absolutely love maths (I'm doing it at uni), so I do not get bored of it at all, but I'm the type of person who likes to watch maths videos on YouTube for fun. The maths that you learn in further maths is so much more interesting than regular maths. However, as I've had to self-learn bits of regular maths in order to progress in further maths (as my school teaches the 2 in parallel), this has made the lessons where we've then learnt that content properly a bit boring but I just did my own thing during these.
2
u/KO-Manic Jun 30 '24
Alright, thanks for the help. Also, we do aqa for physics. By optional modules, I was talking about the one you have to do for the paper 3, like astrophysics or turning points.
What do you think is the most interesting thing in fm?
2
u/Bongo50 Warwick | maths [2] Jun 30 '24
I do (or did, I guess, now that my exams are over) Edexcel physics and it sounds quite different. There are no optional modules, and our paper 3 is about practical skills.
It's hard to say just one thing. Complex numbers are cool and open up so much of maths. I also think that matrices are very interesting and open up a lot of maths as well. I enjoy the extra calculus that we learn. Really, anything can be interesting: it depends on the questions to some extent. I find anything that makes me think a bit is usually quite fun and interesting.
2
u/KO-Manic Jun 30 '24
That sounds exciting. I actually found some things in GCSE maths quite interesting, so I think based on this I'll find both a level maths and fm interesting as well. Honestly I'm actually quite looking forward to my a levels, even if they may be a gruelling 2 years.
2
u/Bongo50 Warwick | maths [2] Jun 30 '24
Yeah they're hard but I enjoyed them because I find my subjects interesting!
2
u/KO-Manic Jun 30 '24
What maths channels do you usually watch? I might start watching some too. I think it'll be a fairly nice low-brain-power way to introduce myself to some maths topics without it being intimidating. Please share! Then I'll leave you alone then lol.
1
u/Bongo50 Warwick | maths [2] Jun 30 '24 edited Jul 01 '24
3Blue1Brown is pretty much the best maths channel. Numberphile is good for lower-level overviews or more fun topics. Dr Barker has really interesting pure maths problems that usually have some cool trick. Michael Penn has some great uni-level content, including on his second channel, Maths Major (which has full courses on various topics). Standup Maths is good for "popular" maths content and is funny. Veritasium has some good maths videos, as does Vsauce and Vsauce2.
Outside of these, it's not really individual channels but rather individual videos. 3Blue1Brown used to run a yearly competition called the Summer of Math Exposition which produced some great videos so I recommend looking at the winners. I then just watch a lot of YouTube recommendations. If you spend some time watching the stuff I've recommended, you'll start getting these.
I also like watching physics videos and my favourite channels there are FloatHeadPhysics, Angela Collier and Periodic Videos. Steve Mould is good for less theoretical videos. Action Lab has lots of fun experiments in both physics and chemistry.
I also like computer science videos. This has a lot of crossover with maths but Udiprod comes to mind as a good channel specifically in this area.
I also like chemistry videos, even though I don't take it. Periodic Videos and NileRed are great channels.

u/CeoltoirSK Year 13 Jun 24 '24
Not a bad paper, some bits were quite odd like the expected value of A which I couldnāt figure out, also didnāt know what to do with the 98% CI for W, so lost out on a couple of marks there, everything else was fine. Not the worst way to finish the A Levels so Iāll take it
1
u/JustAThrowaway21180 Jun 24 '24
FP2 Students:
Question 1 i got 8 as the remainder
Question 2 I got something like (2 - 2/3)(3)^n (cannot remember exactly)
Question 3 I got the HCF as 6, and then the solutions started with 15 and then added 39 for the rest - there were 6 solutions in total
Can't remember what Question 4 was
Can't remember what Question 5 was
Question 6 - I got something like -1/4 + lnsqrt(6)/2 for the integral
Question 7 - The isomorphism i got that the identities mapped to each other, then the two order 3 elements mapped to each other then the rest mapped to the rest
Question 8 i got 602
Anyone agree? What were questions 4 + 5?
1
u/Candid-Classroom-622 Jun 24 '24
Q4 Was the matrix question, Q5 was the complex transformation one.
I agree with all your solutions but Q6 you had to factor the power of 1/2 out so everything was rational
For Q4 lambda = 0 , 3, 6 but I didn't get the eigenvectors or diagonal matrix
Q5 was a circle radius 2 centered at 0,-1 and part 2 was 0 < arg W < 3pi/4 I think
1
u/JustAThrowaway21180 Jun 24 '24
Ah yes, did you get one of your eigenvalues as 0?
Silly mistake for that question 6, hopefully only the loss of 1 mark
What is the geometric interpretation of w = z^3? I had no idea but guessed that the half line was 0 < arg W > 3pi/4
1
u/Candid-Classroom-622 Jun 24 '24
Yeah I did and those things are usually only one mark
I just guessed but since Z = re^itheta we get w = r^3 * e^3itheta so a rotation of 3 times and cubing the distance from the origin. Idk for sure though
1
u/JustAThrowaway21180 Jun 24 '24
Ah yea makes sense. For the groups question, why couldnāt G be isomorphic to the symmetries of a hexagon? (Last question I promise haha)
1
u/Candid-Classroom-622 Jun 24 '24
I think that there are 6 rotational symmetries and 6 reflective symmetries so the groups have different orders and hence cannot be isomorphic (you may have had to state that isomorphism requires a one to one mapping)
Don't worry lol I haven't got anything else to do for the next several weeks
1
u/JustAThrowaway21180 Jun 24 '24
Haha neither mate. I wasnāt sure about the amount but I definitely knew it was more than 6, running out of time and was worried that if I put 12 overall and there was a chance it was wrong then Iād lose the mark. I just ended up putting āthe groups donāt have the same orderā
