STEP Prep Thread 2016 (Mark. II)

Being honest if you found a paper tough - it was a tough paper. I'd bet anything that you've done much better that 2 fulls and 4 partials in STEP II papers plenty of times before, so you should be expecting lower grade boundaries no? Did you find it considerably harder that usual ones?

Can someone please explain how you draw graphs when there's tons of variables?

Like the fn(x) one? Drawing the graph for a specific n value is hard enough how do you draw a general graph to cover all n values??

you didn't need to
you needed to do sketches about parts where the roots a and b were. the rest of the graph was irrelevant

1-18-20 (check the graphs on wolfram)
7- 12-13
6- 10
sorry cant help you with 9 or4
11- 15-16 (felt maybe the last part was the important part bringing i) and ii) together of the question but idk)

Which question?

People who did 12, if the answer they gave you for the probability of at least 1 out of n being in its correct place is f(n), then isnt the probability of exactly one being in its right place n(1-f(n-1)) as you choose 1 card to be in its right place in n ways then times by the chance that all the other n-1 are in the wrong place?

I usually fail in exam conditions, every single one of my exams this year, be it A-Level or STEP have been a disappointment. It seems like other people seem to have fared okay though, so I wouldn't use my own experience. I'm just retarded.

But how? Am I missing something here?

Which question?

Edit: Ah, I remember. That was a nice question! No, just sketch around the roots a and b, not the entire graph. We know the gradient, so...

Did anyone get values for x and tan theta for the trig inequalities question? Also how many marks dropped for doing everything but finding the values?

Thanks yeah I'll check

EDIT : Do you think I missed out on any easier pure question(s)?

x=+-1 and tan theta is -1/y i think.

I did question 12, and someone else agreed with me that it is just (1 - f(n-1)).

n cards that can be chosen * 1/n probability that chosen card is in the right place * (1 - f(n-1)) probability that others are in the wrong place.
