I did questions 123567 and I think it went relatively well, especially compared to Step II. Let me know how you guys went!

Question 1 was a really nice one to get going I thought, and then I just worked through 3,4,5,6,7 to varying degrees. How much of your six did you complete?

Yeah Q1 was really nice, but I think I rushed Q6 because i did it at the end. If i'm lucky I'll get 10-12 points
I fully finished 5 pure questions and completed more than half of Q8, I think this paper is much easier than paper in 2023 and 2022, so the score boundary shall be higher this year, I think?😝

By the way, STEP 3 this year is much easier than STEP 2!!! I hope that I can also get a S in STEP 2😭
I would really appreciate it if anyone could give me a rough estimate of what I would get on this paper. I’m not very good at estimating at all. (I need a 1 but I’m doubtful that I got that.)
I completed Q1 fully.
I then went on to do 5. I managed to complete part i and ii and then showed that det(M), tr(M) and tr(M^2) are all independent of t.
I then tried Q2 which I think was the one with the modulus functions. I tried doing a(i) and a(ii) but I think I made a silly mistake on a(ii). This was definitely my least successful question with some attempts at several parts but not much substance.
I then did Q11 and I completed all parts except the very last one.
I then tried the sums question with f(n) and g(n) (I think this was Q7) and did the first two parts (finding the range of f(n) and g(n)) but got stuck on the third part where we had to show those two expressions were integers.
I finally tried Q3 (for what value of c the function is increasing and decreasing). I got as far as sketching the function for the two c values given. I checked my graphs on Desmos and they are correct.
How do you think this paper compared to previous years? What do you think the grade boundaries will be like?

rewarded 20 for Q1
rewarded more than 13 for Q5(since I finished all of them and I think that the last part is much easier than the part before)
rewarded around 10 for Q3(maybe, this question is straight-forward for me so it is hard for me to judge which part is more difficult, but I think this estimate is fair)
rewarded around 5 for Q7(because I finished it and I'm sure that the part behind is more tough)
I didn't do Q2 and Q11 so I won't give you an comment about those questions🤣
Add all of these and then minus 5 for silly mistakes, then you will get a relatively reasonable estimate

I think it is easier, and maybe ~90 for S

what do you think for a 1? do you think it would be above 70?

nope, less than 70 I think, 70 is tooooooo high!
For question 2 with the modulus did anybody get these equations https://www.desmos.com/calculator/kbqliyxove
My son said this paper is harder than STEP 2. Maybe he is good at number theory and STEP 2 has quite a few number theory questions.

was it that you had to show that they were independent of t, or you showed them individually without using t? Sorry, just a bit worried because of my terrible reading skills, tend to get way to rushed into questions. feel free to repeat the question aswell

d(what you want)/dt = 0 is what you need to show

i did fairly similar to you, although I tried the coupled DE question instead of Q2, (I didn't get far) and I didn't do Q11. I reckon you've probably got 40-55 range, I mean, I have no idea obviously but usually if you're gonna get a 1 you need to get further in a couple of questions. I haven't done any better

How were you supposed to show that the particle goes through the origin at t=T in the coupled DE question???

how did you show that a turning point exists for q3?
What was question 4 if anyone can remember?

What was question 4 if anyone can remember?

I think it was the one about the lines meeting at 45 degrees and you had to show that (m2-m1)/(1+m1m2)=+-1 and then it went on to use the y2 =4ax curve
did any of you guys did q3? how did you do the final 2 parts??
