Can a 100 scale down ever ? Even if the whole state gets 100 ?

For Question 14 part c ii), I put the same answer in the solution, but didn't put a 4C4 in front of the first term, because it equals 1. Would I lose a mark?

No, you definitely would not lose a mark for that. The reason why I left 4C4 there was to continue the pattern of coefficients.

Doubt it.

Hard to say. This paper was significantly easier than previous years.

The chance of that happening is so small that one could be forgiven for not having a plan in place in case that happens.

For example it says "find an expression" is this the type of things that also differentiate state rankers? Like I found the expression and gave the solution?

Not something I can rule out, as I don't know what process they use to differentiate state rankers, but unlikely they'll nit pick over silly things like that.
