Design an A4 poster, 8x3 banner and A2 poster to advertise our student promotion

Offering students the opportunity to join the gym using all classes and fitness facilities by purchasing a £25 for 25 days or £50 for 50 day pass.
This is to attract the student market so images much relate to this age group - these will not be supplied.
Positive and energetic imagery relating to students, the gym and exercise classes to be used.
Logo's will be supplied
I am happy for the designer to have their own ideas on design and layout as long as certain brand guidelines are followed.
