History or Chemistry A Level?Watch
I did chemistry at college, and I remember in the early days that I just wanted to drop it. It does get better and more interesting though if you stick with it. I haven’t done history so can’t help you there, but if you think you would prefer history then you will probably get more out of it in the long run. Although you may be better at non-essay subjects now, that can change and you might end up getting a better grade in history (a subject which you like, and so will be better motivated for) than you would have got for chemistry. If you still want to do something in STEM at uni, maths is considered a science so that door is still open if you drop chemistry.
