Not a predicted paper, but I would highly recommend doing the 2019 D1 paper as iirc it has all the adv info topics in the paper + CPA scheduling. So that can act as a nice predicted paper.

do you guys think they will ask about two stage simplex? i feel it is unlikely as they've put big m method as a bullet point on the advance info.
Also what do you think they will ask us for the bullet point "formulating and using simplex to solve a linear programme" will that just be the usual?

I think only big-M, and formulating linear programme yh just defining variables and writing constraints and objective function from some bare wordy thing.

I've been taught the core pure in school, but the decision has all been self taught.

hopefully it won't involve any solving things graphically because I always do that wrong. I just struggle so much to draw all the lines on correctly and shade out the correct side, like idek why I find it so hard. I much prefer simplex.

Has the potential to, although there are two bullet points on the advanced info with simplex, so im guessing one will be formulating it and like an interation of first stage simplex. And then big M

It's so frustrating sometimes. Decision is the paper where I make the most stupid errors. Especially if I have to add up lots of numbers, as sometimes I'll just miss one out and get it wrong
