Speak with the school’s careers adviser or Head of Year to gain an understanding of how the subject option blocks have been put together. Ask if the GCSE classes are taught in mixed ability classes and which teachers will be taking each class or block and therefore teaching your young person.
If the young person has a career path in mind, think about what subjects are most relevant. If they are interested in a career related to science, then they should think about doing double or even triple science at GCSE.
If the young person knows they would like to work abroad, then studying a language at GCSE will help them with future employment.
