I am completely finished, that exam ruined me. I've been getting 95% or above on every mock I've done and today I'll have been lucky to scrape a C. There are actual tear stains on my exam paper, I have never cried in an exam. That was dreadful. I needed to get an A in this so I could fail c3 and c4 but pass overall, now it's logistically impossible for me to pass maths a level.
When I saw random numbers on the first question I was gutted, I'm good at that and I knew it meant there would be the other topics as long questions. Why only choose 3 numbers? Question 2 on graphs is pretty much the only graph question I've ever understood. Question 3 was ok can't really remember it. Question 4 I had absolutely no idea, what were you meant to define X and y as since you already had X and y in other things? I rearranged for z but can't have done it right because the graph was completely wrong, so there's 16 marks out the window. Question 5 was CPA and scheduling? The network was a bit weird because of how many start activities and dummies but I think it was right. The scheduling I got myself in a tizz about though, I had it so that you had to stop halfway through an activity in room 3 when you reached the 6 weeks, then wait for activity in room 2 to finish then continue it after. So that was wrong. Question 6 was prim and kruskal etc, think that went ok but couldn't make a good answer to if you did 2 lots of dijkstra whether that would be easier or not.
Overall I reckon 48 ish at absolute most for an A. I've done a paper with 51 as an A and that was still quite easy, I'm praying for ridiculously lower grade boundaries meaning I get a C.
