Model answer 
I play the guitar. I have to practise every day during the week for half an hour but I don’t have to practise on 
Sundays. I’ve got an exam next month so I must be ready for it. Music exams are hard but you should enjoy 
playing too, so I play my exam songs and songs I really like too. Mum says I shouldn’t worry about the exam – 
it will be fine!
