Paper with model answers

Note that a slash, /, indicates alternative answers in the model answers/mark scheme.

Numerical answers are routinely given to the same number of significant figures as (the smallest number) given in the question, unless the question asks for a specific number of sig figs or decimal places.

Also remember that error carried forward is permitted when calculations are marked (this means that you will be given marks for carrying out the correct calculation, even if your numbers are incorrect because of an earlier error) so always show your working! Marking notes are shown in green.
