Everyone laughs at my inability to do decision papers bu I honestly prefer maths that you know is based on solid principles where you know that your solution is about right (e.g. pure or stats)!!!

i agree coz they are still developing the idea of decision maths and what most of the people who discovered these apparently mind blowing stuff like simplex are still alive and well...but hey quadratic functions and those more normal maths, they have been around for centuries!!!

If its any help, the D1 mark boundaries for June were very low - just 46/75 for an A! Can see rest of data at bottom of this examiners report: <a href="http://www.edexcel.org.uk/VirtualContent/48841/GCE_Maths_Subject_Examiners_Repo rt_Jun03.pdf">http://www.edexcel.org.uk/VirtualContent/48841/GCE_Maths_Subject_Examiners_Repo rt_Jun03.pdf</a>. Having said that... only 20% of those who sat got an A compared to S4 where 51% got an A!

Don't suppose anyone managed to swindle a copy of the paper after the exam or know of any method by which I can get hold of a copy. Im really desperate know how I did now, I should be revising for P2 but this is really bugging me now!!!

Also, I remebered that I got 11.1 for the route inspection (chinese postman) problem and for the second bit I found that it didnt matter if he started from home or not, the route was as short as it could be.

I found that i got a smaller route with starting from home cos only 1 route needed to be repeater. Cant remember my first ans tho

I dont get it.

If the paper is harder, then you wouldnt need quite as high a raw mark in order to get the same UMS as on an easier paper.

I tried to find a shorter route but I got 11.9 as the smallest possible if he walks from home to work first. I found that he only needed to repeat one edge also but it was of length 1.5 so I went over the length of my first route!!!

I got that the extra 2 paths in the first part of the q had a total of 2.2. Therefore the answer for part b was 2.2-1.5= 0.7 i.e. 0.7 km shorter. dunno if its right tho . That paper was a nightmare!

This is a module for further mathematics, I really haven’t enjoyed at all. First of all I suppose it's the fact that none of my universities require further maths so I haven’t really focused on it (kept to my P2, which is on Monday). As my further maths lessons was also on Wednesday afternoon, late last year when we was doing the 'harder' topics, linear programming etc. I was away, so had to try understanding it myself.

As for the exam, I suppose it was OK. A lot of the questions was easy imo, such as the first, second, minimum spanning tree and the postman problem. However as for the linear programming, I didnt have a clue really...

I think your probably right on that one then!!! I think I may have counted on of the edges twice or something!!! This is why I really want another look at the paper!!!

Take my philosophy - What's the point? The paper is sent away and you cant change anything now.

Lol dont worry. just forget about it. I find that whenever i look at a paper again i just see loads more errors i have made. That paper was quite impossible, esp the linear programming q.

I suppose you both right, I guess even if I do get something absolutely horrific, I can always re-sit (again) in June along with pretty much every other maths module I do!!!

Decision and Discreet.

On the OCR (MEI) syllabus it deals with things like heuristic algorithms, sorting algorithms, critical path analysis, linear programming, graph theory, simulations and networks.

Traditionally it's supposed to be an easy module, do it if you have the opportunity.
I really messed up this exam!! How did you find the last question -linear programming? It was something that I'd revised quite a lot and that I'd done quite a lot on but when it came up in the exam I just didn't know what to do! Luckily, I think everyone else found it quite difficult as well -some people were almost in tears (no exaggeration!)

The situation at my college was totally different, people I know were talking about they found it so easy compared to last years. I felt about 2inches tall and wanted to crawl into a hole when we were walking out.

Was your feasible region quite small and in the centre of the graph??? I got 36 and 29.5 but I wasn't really certain. Surely there is a bit of room for inaccuracy because everyone's drawing will have been fractionally different???

! :confused:

Personally, I thought in order to plot z=2 you had to create some sort of new fourth dimension so I can't really help you there.

On the upside I think I did well in my economics exam this morning
