I'm a relatively specialised tutor, I only teach Religious Studies & Philosophy A levels and the Philosophy pre-u. I have a degree in Philosophy and I've been tutoring for 8 years but it's still a lot of work for me to be on top of the syllabus since there are 4 exam boards for religious studies and different schools teach different religions. Even just learning the Christianity stuff for the 4 exam boards is rough as they are all quite different. I look at other tutors who teach my subjects on the various websites and see that they tutor a few other subjects too, sometimes many other subjects. I am wondering... how do they manage that? When I turn up at a students house for the first lesson, sometimes they have an idea of what they want to cover, they mention the topic name and then look at me expectantly. It's taken me a lot of work to be ready for any such topic and I just don't get how someone could tutor multiple A levels and still deliver a really in-depth exam-orientated lesson on any topic. Am I missing something?
