Study advice please — A Levels

For biology the markscheme is really picky so you need to do past papers and familiarise yourself with the mark scheme and how to structure questions. For chemistry, try to do past papers and go over the topics you find difficult after the lesson so you don’t have to rush everything before the exam. Also for chemistry, I used to use allery chemistry to explain the topics that I was stuck on. Also PMT for bio and chem is helpful. I used to watch Ms Estruch for biology. For psychology you can use a flash card app called gizmo and it tests your memory. Also Knowunity is good. Tutor2u and psychboost is good

My subjects are:
OCR A Biology
AQA Chemistry
Psychology (haven’t been told yet)
I was wondering if anyone had any tips for studying for these since I start in two days. Any websites, tricks etc would be appreciated.
I also know that this a popular combo for a level so this thread could help a lot of people except me and it would be great if even those who are starting sixth form like me could give some advice or tips that they’ll be doing once they start!
Thank youu☺️

for psychology “psychology wizard” is a great site for information about studies and exam essay practice. For biology “my physics and maths tutor” as well as “quizlet” i find are really helpful
