Well I spoke to my school on Monday and they said:
Good morning Michael,
Unfortunately you will not be able to take your GCSE French exams here at the college as we do not act as host centres for languages due to the oral element of the exam. If you need to find a centre that holds the exams, I can recommend a place called 'tutors and exams' which is based in Coventry who take external candidates. The contact number is 02476 221008.
You will also need to find out when your French exams are as you may have a clash on your timetable. If this is the case please let me know.
I hope this helps, any questions please let me know.
Kind regards, Jackie Hands
