obviously not.... all you will need is talent.
YOU NEED GCSEs
you need 5 gcses and 1 a level
well you will need your GCSEs and a level
if its a good job then you need good GCSEs
You can do any GCSE's but you have to have French and you would probably need a C in English, Science and Maths to get into uni in the first place.
