are they that harsh on s.f.
I doubt it... though I think they will be very harsh on units
2. what does error carried follow mean and is this paper error carried paper if so

This is when you get an answer wrong earlier in the question. But you can still get full marks in other parts due to error carried forwards.

It states in the mark scheme that you can not lose marks for s.f unless it states for an specfic s.f or you round too early (1s.f rounding = very unaccurate. You only do 1s.f rounding when its about uncertainties).
4. does anyone know that if you just put the answer down but no working out, would you still get all the marks if it is correct
5. anyone have an unofficial mark scheme?

The maximum amount of marks you can lose for unit errors is two. That means even if you don't put units on any of your answers throughout the whole paper, you will only lose two marks.

I'm pretty sure you only get the answer mark, no method marks.
7. btw what was the answer for the initial velocity
8. (Original post by MukhtarA)

8?
acceleration was 3?
final was 23?

think initial was 8, acceleration was 6. final was 38

fffssssss

fotgot it was '1/2' at2 dammmmmmmmm

i should get error carried forward on the final velocity though i guess -.-

Yes, not to worry you'll get all the ecf marks, so you may only drop 1/2 marks max
12. I swear it said it accelerated from rest? So why wouldn't it be 0 for initial?

thats exactly what i put down but then using that answer, the next part seemed wrong

Someone explained it to me today. I must have imagined it started form rest but it never actually said it anywhere. Silly marks dropped there
15. can anyone post the actual paper up
16. yeah i got 6 ohms, what name is given between point A and point B on a circuit. this was for 2 marks.
