The General Certificate of Secondary Education (GCSE) is an academic qualification in the United Kingdom, typically taken by students aged 15 to 16. It covers a wide range of subjects, including mathematics, science, and languages, and is designed to assess students' knowledge and skills at the end of their secondary education. GCSEs are important for further education and career opportunities, as they are often required for entry into colleges and universities. Students usually take multiple GCSEs, and their results can influence their future academic and vocational paths, including options like A-levels or vocational training.
