Found it harder than I thought it would be. I couldn’t answer quite a few questions. Think it was harder than last years paper

Did anyone actually manage to find a cut of 97? Or was 97 not even the correct answer for the maximum flow. Ffs

I think it must have been 97 as when you added up the values that were in the objective function it gave that answer. There must have been one of those really weird long cuts for that answer - only one mark though. What did you get for the very last question?

Lots of people from my school said it was hard, so the grade boundaries will have to be very low. I have to take it tomorrow as an internal exam, what important topics are there?

I subbed in z = x - 10 (or whatever it was meant to be) and must’ve f**ked up somewhere with rearranging coz got y intercepts of 44 (can’t remember the other one) I’ve heard a few people I know saying 63 tho. I can’t even remember what I got aha.

Yeah I did the substitution too. I think it was z=2x-10? I dunno. Can't remember my value for P tho. I think I got x=8, y=0, z=6 or something along those lines. I only managed to find the cut of 97 literally in the last 30 seconds of the exam, I got so panicked trying to write it down.
