# AQA Mathematics MD01 Decision 1 – Friday 24th June [Exam Discussion Thread]

1. 64/63 for A?

Attachment 556247 The vertex question part ii) was something along these lines where the graph was semi eulerian and had 5 vertices and was a tree
I don't think that's a correct tree. A tree is a graph without cyclic routes, and this graph is cyclic

It was not

"Twice as many as x as y". So if y was 50 then x would be 100.
Yeah it was, my mistake. See edit
4. Is there a D2 thread anywhere?

I don't think so

That's correct. The vertices B and D needed to have an odd degree, so the shortest route between the other two odd vertices (12) had to be added to the total weight of the edges in the graph. The start vertex was B.
WHOOP WHOOP! loved this exam!

Yeah it was decent, I think decision papers are always pretty similar every year

Did you get 520 for the profit aswell?
I got £515 in the exam for some reason, but the answer is definitely £520
11. (Original post by tajtsracc)
Ah okay, I'm curious why you think it's definitely 520? I really hope it is lol
I checked the answer on Wolfram Alpha. I've copied the link below if you want to check for yourself

No problem!
13. Why is no one talking about D2??

Because a grand total of 4 people take this exam
15. D2 should be good

Haha no, I was just underexagerating , however in my year there's only two of us doing D2 tommorow.
18. Yeah there aren't many at my college doing it. Anyway how are u finding it?

Not too bad, I find the algorithms and techniques to be simple, however the difficult part for me is needing to apply knowledge in some questions rather than just getting on with the working
20. Oh right so things like those worded dynamic programming problems you find hard?
