If you want to be an advertising copywriter, check out the IPA Copy Test website (click on 'new user?' for details). You will have to answer 6 randomly generated questions in an hour.
Then you can choose to submit your entry into the IPA Creative Summer School competition, with the opportunity to win a placement, either as a copywriter or as part of a creative team, over the summer. Or you can choose to submit your entry to a Copy Showcase, where it will be stored for one year. IPA members will then be able to access and consider your entry should any creative writing opportunities come up at member organisations and agencies.
The placement will run for 5 weeks (6th July-10th September). The deadline for entry is 12th June and the competition is open to second and third years and recent graduates. Students will receive £500 on completion of the placement.
