DEs? Those are normally pretty easy... I am assuming there is some cruel twist to them.

You should be able to go through those.

Is there a PDF question?

Nope, two expectation or expected value problems.

Hmm, they are not my favourite but I'll give them a 2-minute skim to see if it is worth doing them -- but of course I will try to get the easy ones out the way first (DEs). The grade boundaries are:

S - 84/120

1 - 65/120

2 - 53/120

3 - 32/120

They do not look easy and there are parts.

If I had to guess one of them is probably about transforming a DE into another using some obscure substitution, then the last part probably gives you a DE and expects you to use a similar substitution...?

The first question is the DE's They want you to solve one and it looks okay.

The first question supposedly has a massive typo in it that resulted in lots of candidates losing time...

There is a strange part in it.

I guess I will have to find out what it is when I do it...

Lots of people skipped it.

You are reading the examiner reports?

I find some of them pretty funny but some also quite condescending, calling candidates pathetic and other things...

I am looking at the solutions to it.

Where are the examiner reports?

There should be a link saying 'Report' next to 'Solutions'.

In the student room?

That is okay, there are interesting comments in there. I am going to go offline for a bit I need some rest. See you later.

Hi;

That is OK, I am guilty of that too.

A bit annoyed at the moment -- started my STEP III 2012 mock and my sister came in my room and I had to do something for her which took about half an hour. No more exam conditions for this paper anymore...
