Last year when I was fourteen, I started my GCSE course. GCSE is short for General Certificate of Secondary Education. The course runs for two years. All of us study English, Maths, Science, Information Technology and Religious Education. We also have optional subjects to choose from like Languages, Business Studies, Design and Technology, Music, Geography, History and many more. At the end of this two-year course when I'm sixteen, my teachers will give me grades in some of the subjects based on the standard of my coursework over the year. In the other subjects I have to take GCSE exams to get my grades. We can take a minimum of five exams in optional and compulsory subjects, but most of us are going to sit about seven to nine GCSEs. It seems a lot, but one can do even more. I heard that in public schools they take up to twelve GCSEs. Just imagine doing that! However, there's a good reason for this. These exams are extremely important for one's education and career. If you decide to leave school after doing your GCSEs, your employers will always want to see your results before giving you a job.

GCSEs are graded from A (excellent), the highest, to E (satisfactory), the lowest. If someone fails GCSEs, it's not the end of the world: one can resit GCSEs later, but it's not an option for me. At sixteen, after finishing their GCSEs, some of my classmates, who are not academically minded, will leave school and start looking for jobs. I don't think it's a great choice. Nowadays you can't succeed in life without having a good education. I'm planning to go on to the sixth form. This is a traditional name for the last two years of school, which are optional. During these two years students do their Advanced Level course and get ready for their Advanced Level exams, which are usually called A-levels. These exams are taken at the end of the school year and the results don't come through until August. They are absolutely necessary for those who want to get into university. A-level students choose their subjects according to what they're planning to study at university. Most universities will accept applicants with two or three A-levels, but for some top ones students may need to have more. And they may need to get straight As to win a place. To be honest, I haven't chosen a university yet. I haven't even chosen what I want to do. I think I still have a bit of time for that. Anyway, after doing my A-levels, I'm going to take a gap year before university. During that year I will have a chance to see the world, try some different jobs and decide what I want to be.
