history or economics

I am very unsure of what to do. I am studying A levels in History, Geography, Economics, and politics and I need to drop one. I attained a 92% A* in my History GCSE so took it to A level. I am currently doing the OCR in history ln Germany (which I did for GCSE) Pitt to peel and civil rights. I am finding it ok and have done well in essays on Germany (3x17/20) and pretty well in Pitt to peel (13/20) which is good at this early stage, however, i am worried whether the workload will become too much as I already spend about the same amount of time on history as I do all my other subjects together due to all the essays and would like to know if it gets easier or if it is very hard the whole way through with all the material to learn etc.I am however interested in economics but am admittedly not the best at maths with a B at GCSE. I am not grasping the subject very easily as I lack the graph/numerical thinking but I have been improving with repetition. So I thought if I drop history then I will have more time to focus on clarifying the lessons work, but cannot obviously see this until I drop one. Has anyone initially struggled with econ and found it improved? I am just thinking about all my sports commitments outside of school starting next term if history will become too much as I already find it hard. any advice or on your own experiences? thanks.
