Hi I'm starting a PGCE in FE in September. My main subject is philosophy. This subject, in effect, gives me two A level teaching subjects: philosophy and critical thinking. In my research into FE teaching, I have come across many cases of people teaching A level subjects for which they have no subject-specific qualifications -- they have simply gotten hold of the syllabus and dived in. With this in mind in relation to my marketabilty, I am wondering what additional subject I would be best off developing. I have an interest and some knowledge in religious studies and psychology, and my question is this: of these two subjects, which is the most marketable in terms of demand for teachers?
