STEP Prep Thread 2016

Wow amazing! Im guessing you were in the post 100 club then for that paper :wink:

I should really look more at the applied qs, never done one in my mock before! Q14 looks meaty for a stats question. If it was a person I reckon it would be a large american guy who loves his steak called "Big Bubba" or something :wink:

I'm dying at "Big Bubba" lmao :rofl:

How'd you find the mock then? Which Qs?

I'll post my thoughts when I'm back home. It was a nice paper, though.

Don't you do your mocks at home?

Yeah, I did. But I had to leave as soon as I finished.

Could I get a hint for II 1994 Q4 Part 2? Struggling to see where the arcsin(c/a) has come from! Also if anyone's done this question, what did you think of it?

Nevermind got it in the end, not sure about the last part though.

For STEP I 2014 Q 6 final part, do you need to explicitly state that the sequence is {1, 3, -1, -1, -1, ...} or would you get the marks for just putting the nth term?

I think you'd lose a mark for not stating that the sine term is zero for n > 1. So if you give the nth term and state n > 1 means sine is 0, then you'd get all the marks.

Cool, thanks.

Yeah, I tend to always start off my mocks in order, so doing Q1,2,3 if I can, even if I like the look of something else, I kind of "save it for later"

Q7 was lovely! It was the first thing I tried as well and it was so good. :biggrin:

For Q4, you'll want to shoot me. I didn't think of doing what you did, I only realised after and it was so simple. :facepalm:

I collected

\sin 3x - \sqrt{3}\cos 3x = R\sin(3x - \alpha)

...

And yeah, the 'trick' was the identity in part (ii). I actually kind of half-grinned at that. :lol:

But yeah, that Q4 thing was annoying. Did you use integration for (iv)? I'm quite happy I spotted the symmetry trick.

Well done to both of us, I think! :smile:

That's what I read on the solutions for Q4, so I thought many people must have done it that way; I certainly prefer my method :biggrin:

. But no I don't want to shoot you haha.
Tbf with the similarity between (i) and (ii) I knew the only difference worth putting in would be that (ii) was an identity so I expected it :wink:

.
No I didn't use integration, but I feel sorry for those who rushed a little too much and did! I did realise that the symmetry thing must have some significance and it was easy to see that the area was half the rectangle :smile:

.

Q4 was actually a ridiculously short question looking back, unless you're stupid like me and start the question using the QUADRATIC FORMULA to get expressions for b and c. When I got the expressions I realised immediately that their simplicity was certainly not a coincidence and made a little 'note to the examiner' that I realised that sum and product of roots would've been much quicker haha.

All in all a great, enjoyable paper :smile:

. Gonna do III 2010 tomorrow I think (although possibly will change my mind and do 2004, haven't quite decided yet).
