Just a little question, since you saw the moments question which was worth 14 marks in total.

How much do you think I would lose if I did everything right in part (a) but wrote the final answer incorrectly because of an calculation error I did 250/12 instead of 250/10 hence got part (b) wrong because of the last part but I did also use the right methods in part (b)?
I believe the mark scheme will be set up like this:

M1 - Set up first equation using moments, A1 for setting it up fully correctly
M1 - Set up second equation using moments, A1 for setting it up fully correctly

Then there will be M1M1 for solving the simultaneous equations using some method, with the final two marks being A1A1 for each correct value.

So I can lose up to four marks?
3. Can you get Solomon papers that are like whole past papers? On my school server the only ones are whole sheets of a topic each, if you get what I mean.

Well done! I was annoyed because I was hitting 70+ in my past papers, then bam! Hard paper and got 65 raw marks...
Thank you what I'm trying to say is M2 isn't much harder than M1, a little more calculus involved is all, is that your M1 score from January or is that what you've worked out you got in the exam in May?

Yeah, I didn't see it as much harder, maybe moments on planes?

That's my official result... 85 UMS!
7. Thank you very much, just what I wanted

If you've done completely right in part a) but got the incorrect answers due to arithmetical errors, then you will lose 2 marks. I don't know how that would affect part b) though.

Wait and see what mark you actually get before making a decision like that. I don't know and you don't know how that mistake will affect you. The only thing that is fairly certain is that you will lose a couple of accuracy marks on the first part for not getting the correct mass/center of mass. You may well get follow through accuracy marks on part b) (I would be surprised if you didn't) and certainly would get the method marks for it provided you tackled the question correctly.

Well the only the only good thing I see is that I'm still in year 10 so I still have got some time. But I will eventually find out. Maybe the grade boundaries are going to be really low, I can only hope.
12. did anyone else's c3 cw get marked down? My entire class got four marks deducted by moderators. I would have got full marks My teacher appealed but the appeal was rejected.

85 is pretty good! Erm the moments definitely get more complicated, but there is a pattern to the questions which makes it easier

Sorry to intrude but what would you say was the hardest part of M2 for you?

Hey DJ What do you think about the marks for the motorbiker and exerted on pulley question? I carried the wrong time over of 100 seconds (yes massive mistake) and for the exerted on pulley I stated a direction and wrote 2Tcos45 but somehow got the wrong answer of 12 root 2

I did the edexcel spec, and it's quite hard to say, all the topics are manageable but it just depends on what sort of question they give you. Personally though, I'd say Statics of Rigid Bodies, but you could get a really nasty question on Collisions like I did in Jan and you do have to look out for Kinematics sometimes

Well the thing I tend to struggle with is the Work-energy principle as I'd rather just use M1 techniques as I can't get the concept straight in my head yet, everything else tends to be alright

I wasn't aware there was a math's course work component for any exam board let alone one complimentary for C3!
