The International British Curriculum Advanced level is made up of A Level courses. A Level is a two-year course with internationally recognised examinations usually written at age 18. These two years are split between two courses at CambriLearn: the first year is covered in the AS Level courses and the second year is covered in the A Level courses. This enables students to choose to write only the AS Level examinations, or to proceed to the full A Level course over two years.
