I thought it was a pretty easy paper

Thank you very much! Would you say grade boundaries are similar to June 2010?

OMG, I'm pretty sure my only mistake was giving the magnitude of lambda as -5/3 not 5/3 . I'm pretty sure I'll only lose 1 mark or so.

for the collision, I misread the question and thought it was 2m either side of the particle not 1m, so leading to 25/6 instead of 25/12, how many marks do you think ill lose for that?

Also what do you think the A boundary will be?

Thank you every so much Image

Do you think it's still possible to get an A after doing the projectile question wrong? I assumed that 10 was equal to the vertical velocity not the speed...

Do you expect there to be any kind of error-carried-forward marks for 6b? ie, if I used a different value for h in calculating AB?

Assuming that my method and calculations are right, how many marks have I lost for that question?

I think even though it was easier, this paper was much trickier than june 11... I didn't find it too hard. Maybe dropped 5-6 marks according to your mark scheme but I think it might be a bit lower than june 11

Nah mate I think that will be M1 A1 lost out of 3 marks because we didn't take the correct direction. Probably still get 1 mark for quoting I=mv-mu

I made this mistake too but I highly doubt we'll score two for getting lamda=1/3
