Sure I can! I really enjoyed chemistry because of all the experiments and you learn a lot about how chemistry is applied in the real world which I am sure you will enjoy (my favourite was learning about colour chemistry).
Biology I did like but I found it a bit harder, the human body things were really interesting but the only thing I didn’t like was learning about plants! Even if like me you find plants a bit boring, most of it is about how our bodies work and with some experiments you might even get to dissect and see some animal body parts aswell( more fun than it sounds).
Psychology was really interesting and I loved it a lot but I dropped it at A2 because I really wanted to do maths. I do regret it a bit but I think you will really really like it if you are interested in how the human mind works. A lot of science like the food engineering I am doing ( the food tasting part)is about psychology aswell so I actually still get to learn about it (it’s super interesing aswell 🙂 )
Hope that answered your question, feel free to ask more if you like!
