How many gcse's did Lewis hamilton get?

He received no GCSE's because he was expelled from school, because an incident happened in the toilets and he was only a witness, but someone who looked similar caused the incident and that is why he was expelled. Those details are found from his auto-biography. He studied English, Science, Maths, Business Studies and others. He loved music but as he was interested in motor sport his father advised him to do business studies instead of music.
