Your enjoyment could strongly depend on the topics you study. I take Civil Rights in the USA, the Tudors 1547-1603 and Russia 1894-1941 and I can definitely say that the Tudors are just a bit dry and detached for me. Civil rights though, juicy topic.
My enjoyment of the subject has also been heavily due to the fact that there are only 7 of us in my class and the teachers are all so chilled out.
I take it alongside further maths and physics - I rarely do much history work outside the lessons (maths is like a black hole of productivity). However do not underestimate it, there is a lot to learn. Not because learning facts is an actual part of the course, but because to have a convincing argument in an essay (and it's just essays now) you need evidence and stats to back it up.
Also, coursework. Very very different to GCSE coursework, in my experience. It's not like a long exam-style question, it's more like "explain why there is a debate here"
