TEACHING; What/who/where could I teach with my law degree?

[Washersaurus]

Or is it as good as useless when it comes to enrolling on a teaching course?

Am I only good for FE teaching?

May be try to get A a GCSE maths and do a relevasnt main stream A level perhaps, just to show you are bright enough academically to be a teacher etc. which I am sure you are but on paper it may not appear so.
