I thought it was OK. I lost either 2 or 3 marks (out of 4) on the sinking into the ground question, because I took the force going down as mv instead of mg for some strange reason. I also think I lost 0-3 marks on the 3 marker at the end of the paper because I drew thrust in the wrong direction (but got the correct answer, as a negative, where I simply changed the values on the left of my equations to be negative also so that it fitted).

I'm thinking 69/75 assuming I've made no other stupid mistakes I haven't foreseen yet.

The exam solutions would be just swell right now to put my mind at ease.

Does anyone remember what they got for 2c? The distance on the plank?

I meant he had nailed what the last question would be on, but, yeah I got 0.125N

Hmm, I was so happy that I checked out the examsolutions bit on trust before the exam.

1) V = 1.5MS^-1, M = 0.3KG

T = 115 for that A to B thing

0.316m for that ball sinking into the ground question.

5km for the vectors question, then something like 12.625 for the due north bit.

Thrust = a = 1.25, then tension in string = 1.375, then speed at t = 6 = 7.5, distance travalled = 7.5, thrust = 1/8

Can't remember any more!

Paha, 1/8 N?
YES That was the one I thought I'd screwed up...

Also, does anyone know if you're penalised for giving vectors as columns, as opposed to i and j?

Does anyone know that if you show 2 methods or more, the best one counts apparently? Right?

uh uh. 302 I seem to remember getting. There was a strange sense of deja vu doing that one I think there was an incredibly similar question in a past paper I did...
18. Re: M1 May 2012 Edexcel - Post Exam thread - Paper and Solutions in the FIRST POST
75/75

So long as I get the mark for putting 3 s not 2.99s ?
