Your workings for the MCQ’s will not be looked at.
You will obviously need workings for yourself for some of the questions – you do these in the answer book (but head it up workings so that the marker does not think they are the answer to a section B question!!)
You can also do workings on the actual question paper (and you can do this during the 15 minutes reading time – it is only the answer booklet that cannot be started)
Either way, the workings will not be marked and so don’t waste time being ‘neat’ (as you must be for Section B answers)
