Hi molly, does the job advert really ask for a c.v.? These days it's recommended that people's cv's match the job you're after, so although you need to show that you have your school results they will also want to know that you are good with people, responsible (Cadets should show them this), reliable, you can write down an order accurately - all the exam results in the world won't show them your people skills. If I were you I would write a letter saying that you want the job because.... and explain your skills, and say that your c.v. showing your exam results can be available but you have no printer at the moment - be honest! if the c.v. is a must then copy it to a memory stick and take it to someone else with a printer (e.g. your library) and print it there. Good luck!
