Cardiff University Curriculum Support are linking with schools and are offering a series of workshops and lectures relating to AS Level, A Level and degree level subjects.
Follow this link http://www.cardiff.ac.uk/curriculumsupport to investigate the range of subjects on offer and to register for events. Individuals can attend events once registered or if there is enough interest (eg. a full minibus) School may be able to organise transport.
Why bother? Apart from invaluable subject enrichment, attending events outside school proves you are passionate about subjects and serious about taking studies further. When applying for courses of study after yr12/13 you can expand on the experiences gained in your personal statements.
