wasnt too bad :smile: easier than jan 2012! Its not like Decision is particularly difficult, its just sooo easy to make mistakes, for example today, Ive realised that I accidentally didnt shade the unwanted part when plotting the inequalities -__-

is your 'y' value of 20 a typo? My class and I all got 10, or most of us at least.

I've done a few past papers and things. The first one I did as a mock I got a B and the one I did at home I got a C.
I think the main difference with the two I did was that I was careless in my second one.
From the modules I have taken so far (C1, C2 and S1), I always seem to get better results in the actual exam because I'm more careful with my calculations and such.
D1 is NOT hard once you get your head around the concepts and methods of it.
If you make sure not to make silly mistakes in the exam and make sure you KNOW everything youve learnt, then theres no reason why you shouldnt get high marks.
I found this with my S1 as well, as I got a U in my mock then an A in my actual exam.
Good Luck everyone!

Revision thread for the D1 exam.

I have now included the Jan 2012 paper and model answers.

I will start a new thread and include the paper and solutions to the exam on Friday (Friday night, if I am still awake after midnight).

In the next few posts I will upload some past papers, mark schemes etc

note - I will happily remove anything I have uploaded if requested by site admin.
