It's completely void if they use the word 'hence', I'm afraid. Still, if you did the first two parts with the intended method, then you likely picked up a good 13-ish marks?

10-12 marks, maybe?
Naw I used a different method for those 2 as well. Oh well. Dat sucks.

The last integral was quite fun because when you did it by parts you got

I=some algegra-I-intregral of sqrt(1+X^2) which I found to be quite nice, sucks that I would get no marks for it
2. Opinions on II 2015?

3. Zacken Can you please grade mine too? thnx

Q1) Full
Q2) Full
Q3) Full except for the sin(-4) which I put negative value
Q4) Only did part i)
Q7) Pretty sure got it all right other than the last part which asked for an example
Q8) Full other than the last part. Directly substituted Un= 1/sqrt 5 (blah blah) and real close to simplifying but couldn't finish up.
Q13) Only did i)

Can people start panicking for STEP II tomorrow? Seriously, why is everyone so calm? You lot are insane.
Smart tactic to lower the grade boundaries lol.
5. How are you guys feeling about STEP II? S grade incoming? Let's do this! Round 2!

6. All the best ya'll for STEP II tomoz
7. Definitely an easier paper than average (sorry for those who are hoping for lower boundaries).

In fact, 1-3 were very easy for STEP standards.
8. Anyone know if this would get me a 2?

Q1: Did the first part fine, but for the next two bits I got 300+/-root301 which is backwards and for the 7's I got ((7^7 +1)^3 - (7^4)(1+7^7 + 7^14)) which I think is correct but not expanded out?

Q9: I got what was asked and then for when there was more of the rod after the pole I got -ve for the cos bit

Q10: Got the value for e correct, didn't know how to deduce that e<1/3 so left it out and moved on to find lambda and e where I got 2+root5 and -2+root5

Q11: Showed that x satisfied that long expression then differentiated to find the value of x which was the same as required but was running out of time so didn't do the 2nd diff to prove it was a max and moved on and subbed it into the expression and got a quadratic in cos with u, g and h which solved by completing the square but didn't look nice and can't remember it haha. Ran out of time for the last part
9. Zacken

Hi, would you mind helping me estimate my score for the questions I attempted?

1) Quite sure it is correct. For the proving part, I separated the case n=1,2,3,4 and proved one by one.
2) Did up to differentiation and stopped, not even sure whether the differentiation was correct as it was pretty messy.
3) I think the last 2 graphs were correctly drawn, may made slight mistake in first graph from -3 to -pi(or more), and did't draw for -3 to -pi for second graph I think.
9) First part proved. Second part got the same proof as I forgot to consider the change in frictional force direction.
10) Quite sure it was correct.
11) Results were proven.
12) First 2 parts were correct(where they both shared the same answer). Didn't do last part.

Very much agree. Could be a challenger for 2010 or 2013 as 'easiest paper'. Pity I didn't do as well as I should've!

Q1) 20
Q2) 4
Q3) 15
Q9) 17
Q10) 20
Q11) 20
Q12) 8

100-ish

...
Q1) 16/17
Q9) Are you saying you got a full? 20.
Q10) 18
Q11) 15

Definitely a 2, maybe even a 1.
12. Good luck for tomorrow everyone . Let's ace it!!!

Also any last minute advice/tips/suggestions anyone?
13. Anyone have the paper yet?

Thanks Zacken!! Just to double check, can I get that high for Q9? Got the second part totally wrong and I got the same proof as first part. Thanks again!!

I've posted it twice before on the thread.

It's here.

Edit to add: Solution thread here

I feel like it was first exam nerves for me. I could've upped my marks by at least 15 to be at an S if I realised sooner that you had to choose your own constants in Question 2.

Oh well, I hope the same doesn't happen on the exam tomorrow. I hope I can perform much better, and not let exam conditions get to me.

Btw, any last minute advice (like the user before me asked) ? Any Zacken wisdom you could throw at us?

Really? I'd have thought it would be less than that since all it involved was expanding brackets really, there wasn't anything particularly clever about it. The second part was the 'step' part of the question where you actually had to do something clever.

Agreed with not doing well on this paper. Anywho, tomorrow is the one that actually counts. Let's smash it. Try not to do any maths tonight, relax a bit, remember to bring water into tomorrow's exam, do not panic. Don't rush either, take a few minutes to pick out the best questions, go through them methodically.

You'll do fine!

Thanks, I did try going back a few pages and couldnt find it

Correct me if I'm wrong but Q9's second part was very small, no? Something about changing a positive to a negative?

Maybe 16 marks is fair.

There wasn't anything clever but from what I've seen of markschemes, they have to reward work and there was a fair bit of work done in the first part, I can see lots of (M1 M1 A1) for each of n=1, 2, 3 and then M1A1 for n=4, totalling 11 marks.
