Anyway, I'm also studying Chemistry alongside Biology, Psychology and History. Out of them all, Chemistry has to be the hardest A-Level I'm studying
I do have to agree with you that the questions are quite hard to understand some times but I'd say look at the answers themselves and compare the questions to them. Look at what they want to hear in your answer since answers are bound to given to you.
Look at what you struggle with and learn it by teaching yourself and making notes (when I mean by teaching yourself, I actually mean use a whiteboard sometimes or something to teach yourself like how a teacher would teach a student, it actually helps)
Just asking, what board for Chemistry are you doing at A-Level? I'm currently on Edexcel and mark schemes aren't too bad
In regards to Biology, out of 10, its about 6 in terms of difficulty, if you get the right points you're sorted with Chemistry, its about the application of knowledge mainly with some contextual knowledge being tested out on.
Just learn the content and understand the concepts. Ensure you make notes (I like my notes colourful
) and understand everything before tackling questions and past papers
And yes, Biology mark schemes are more vague than Chemistry mark schemes
Chemistry on the same scale is about 9 out of 10
Hope this helps
