If you are sure that you enjoy a subject but are not sure that it is central to your career aim, then a BTEC Subsidiary Diploma could be the right direction for you.
Subsidiary Diplomas are a two year, 100% continuous assessment vocational qualification, but unlike the Extended Diploma, they are only taught for 4.5 hours a week. This means that the Subsidiary Diploma can be taken alongside a range of other courses.
Study examples
A Subsidiary Diploma is equivalent to one A-Level.
