The pack of exam questions are for your revision purposes.
You will get a booklet of mark schemes for all the exam papers used for these (and other exam questions sets you'll be given). Please do not destroy or lose this pack as we will collect them in from you at the end of the course for re-use next year (they cost a lot to photocopy).
It is probably not a very good idea to look at the mark scheme answers as you do the questions.
