Depending on the examiner there are GCSE Maths exams in Nov, Jan, March and June 2013. You may be limited by which exams are actually offered by the school/college where you choose to sit your exams as a private candidate.
English may be more difficult since there are controlled assessments that have to be done in school/college in supervised conditions and unless you are on a course you may find it diffcult to get this part completed. You may need to delay your plans, join a part-time class and do your exams in the summer.
I'd advise trying to find a centre to accept you as a candidate asap so you know what syllabus to prepare for and what exam options you'd have.
Thank you for all of your advise :-) I think i will just go to college and do the part time course and then do my exams in the summer. Good things come to those who wait. Plus i have to pay if i rush it.
