Physics because you just memorise formulas
depends on the person tbh.
I studied chemistry and biology at A-Level, and i personally found biology a lot harder (probably because I didn't enjoy biology as much). Chemistry AS is fun and not too hard tbh, but chemistry at A2 is horribleee!!!
Based on what I've witnessed a lot of people say; chemistry is hardest followed by physics followed by biology.
Biology. Just memorise everything and puke it all onto the papers.
biology is the easiest by a mile (at AS anyway)
I am currently doing all three (at AS). I feel that Physics is hardest, followed by Chemistry then Biology.
Biology is not hard per say but...
If you read the book and write what it says in the book in your exam you will find it hard to even get a B.
The biology mark scheme is ridiculously specific it's unreal, thus I would say...
Chemistry, Biology, Physics.
hardest --> easiest (to achieve A or higher).
I did AQA chemistry and OCR biology and I thought biology was harder because the stuff is so random and the exam is just hit and miss... The chemistry exam is a lot more predictable and straightforward but some of the content is harder.
Chemistry is harder I think personally. A grade in Biology. .. D/E in Chemistry
I think although the content is SLIGHTLY easier to grasp in biology, the exam questions tend to be harder than those in chemistry as they require you to apply your knowledge and interpret more complex data than in chemistry. However, if you enjoy maths, chemistry may be easier as there is a lot of maths.
I don't think any science, especially at A Level, is easier than the other, they all have their more complex topics and easier topics. It really depends on your strengths, personality and how you approach the course itself.
