yeah..if u look at mark schemes, in questions with linked parts it says e.g. usage of cadidates value for 'x' from (a)...n so if u'v made an error in getting ur 'x' in (a) the subsequent marks r still possible

Heck yeah !

What it means is that if you get stuck, you can "suggest" something, and then work from it - meaning you'll get the method marks, and probably drop 1 or 2 marks along the way, certainly 1 at the point you messed up anyway.

Eg Given ........show that............... and hence show......

so you don't manage to prove the first bit, but it doesn't stop you using the thing you were trying to prove from the first bit and attempting the second bit and gaining full credit for that part.

This is slightly different to ecf, as they give you stuff to use anyway. ecf's do happen though. if your asked to, for example, work out an initial gravitational potential energy, but you bugger it up, then you dont get the credit for it. but if the next bit is maybe finding the final velocity (using conservation of energy stuff where mgh is all converted to EK) then if you do all the right method, even though you have a chuffed up mgh and your answer will be wrong, you'll drop at most one mark for it... ecf's are there so you dont get punished over and over for one cockup in a question...
