H i've just finished my GCSES and did history, psychology, business studies and art as well as seperate science. and workload wise, not at all! Your subjects are fairly light subjects and although it may seem like theres a lot of information to learn in history, if you have an amazing teacher like i did and you are good at quite simply memorising evenst adn dates (quite a bit but definetly manageable) youll deffo cope! just try remeber everything like a story! best of luck
