How is it going? I'm so stuck on D1, the basic questions are okay but it's the ones that asks you to derive eqns for number of arcs, list possible number of nodes etc etc questions that's getting me :frown:

Yeah I'd say I'm similar, D1 is definitely the most time consuming paper I think.

How are you getting past the questions? I'm even considering getting a tutor but seems like nobody teaches d1, it's meant to be a toss module

I just kept doing past paper questions and looking at the mark schemes until I saw patterns really.

I feel like this thread is the epitome of D1 :lol:

I can do all the algorithms fine, but it's usually the wordy-style questions that trip me up...

Anyone have any techniques for the exam? I always start from the back and do the paper backwards, makes it easier for some reason...

Starting to do past papers for this now, I hope we don't get too many long-winded questions in exam, hopefully I can at least finish it! D2 was good this year, so lets D1 will be just as good!

In the last 4 years, grade boundary for an A has been 55 exactly.

Only problem I have is interpreting some questions, like LP, and time.

Hey could anyone tell me where I can find the d1 2015 paper, or post a link? I've done it as a mock and didn't do so well in it so I'd like to have another go.

Is there a systematic way of doing 2ii (in the link I posted above) rather than trial and error?

Question 4 in that paper epitomises OCR's trolling at its finest...

That paper was just disgusting.

The D1 chief examiner is a joker. In D1 Jan 13, question 5 is a LP based in a bakery. The guy is called Roland Neede.
