First, starting a petition is retarded. How well candidates did on average will dictate the grade boundaries, starting a petition so "everybody wins" is just whiny.
Secondly, posting a petition for a core 1 paper in an M2 thread, with the intent to trick people into signing a petition for a paper which they didn't even take, is scummy.
This thread is for the M2 paper, not the C1 paper. Ignoring the fact that your petition is silly anyway, I'm sure that most M2 candidates wouldn't have had any trouble scoring a high mark had they sat C1 this morning.
It is in an attempt to trick people into signing the petition. He replies to comments with the petition wanting us to think it is an M2 petition, not to mention signing a petition for grade boundaries is retarded in itself.
Also hi! I remember you from the COMP1 thread last year.

Can confirm, resat C1 this morning (and found it decent) before getting absolutely rekt by the steaming pile of horse manure that was the M2
1) Car on a plane: i) v = 22.5 m/s [3] ii) P = 35.9 kW [3]
2) Particle up a plane: i) Wd = 8.43 J [3] ii) v = 10.8 m/s [4]
3 Arch shape: i) show that: 13a/3π [5] ii) T = 8.82 N [3] iii) θ = 10.9º left of upwards vertical [4] (or 79.1º above the horizontal to the left)
4 Particle around a cone: i) show that m/6 (2√3 g - 3aω²) [6] ii) T = 39.6N, V =1.19 m/s [3]
5 Ladder: i) show that 5W/24 (1+6x/a) [5] ii) max x = 1.7a [3] iii) tan = 39/14 [3]
6 collisions horizontally: i) a: 5.5 m/s, b: 8 m/s, both in opposite direction to their original motion [8] ii) e=3/4 [2]
7 projectiles: i) 18.8m high, 61.1 m AB [4] ii) 87.3 Ns [4] iii) 11.9 m [9]
Good work you two. Only just had chance to do the paper and I concur with all of these except 1(ii) should be 35.8kW.
It was in my opinion an unnecessarily hard paper. I would guess some very low grade boundaries and, as mentioned above, there's nothing to stop the marks needed for an A dropping below 50; it's happened a few times before (in D1, FP2).

I think that overall the paper was harder, not because of difficulty of the questions, but because of time. I just about finished and had no time to check, and a lot of people didn't even finish, its getting rediculous.
Correct, that's what I am doing. I got 98 in S2 and well...less in M2 so I am pretty sure you can switch em around.
A* criteria correct. Switching gets done automatically, by prioritising:
1. Highest grade possible in maths 2. Sticking to 1, highest grade possible in further maths 3. Sticking to 1 & 2, highest UMS in maths.
Only module restrictions are C's go in maths, FP's go in further maths and if you have, for example, M2 counting towards maths then you must also have M1 counting towards maths.
My guess is most would find it harder than June 2013. Certainly it was more time (and paper) consuming. In fact I used nearly twice as much paper for this one. The only sort of hard question in June 2013 not in this one was the lamina at an angle with both components of the weight contributing to the moments.
For the last part of the last question, I got something like 0.373 something like this..... And I am pretty sure I did make every steps correct, how can you get 11.6?

I had that initially and then I went back and changed it and I can't remember at all what I did
Can someone please help me understand question 4. I know I got part 1 correct, and I got the tension = 39.6N, but I cant remember how to workout or what I got for the velocity. can someone explain the method please

The greatest possible speed with the particle still touching the cone is when Normal reaction force (R) is equal to 0. So using newtons second law, Tsin30 = m(v^2)/r where m is mass and r is radius. Then just solve for v.
How is it that in this paper question 6(i) was worth 8 marks when in the Jan 2010 Question 5, the exact same question was worth 12 marks? How will they distribute the marks out for the question this time?
