We recognise that not everyone should do every subject, but for practical reasons we have to ask them to give it a try up to a certain level. Apart from anything else, this is the most reliable way to tell whether or not the subject is right for them – how can you know that if you haven’t ever tried it? There are many different ways to set this level, and we feel that the current standard is the minimum which will give children a realistic idea of what the subject is like.
