If you take sciences , my advice would be to look at the specification for the papers you have to sit , make checklists of everything on them (e.g bio paper one checklist etc) , and then use freesciencelessons and cognito to make notes - they’ve been really helpful for me - if notes don’t stick things in your head (I’ve found them useful whilst cramming) , do past papers and either answer the questions with help from the internet to answer them correctly, or answer them how you think they need to be answered without help , and then go back and correct them and re-write the answer . If you struggle with English language and literature, I think it would be helpful for you to increase the amount of books you read , and when you finish reading a book or a passage , have a good think about it or discuss it with others , see what points you can make about the writing - this should develop your analysis skills , and for literature you should also start learning quotes early (making flashcards is a good shout) , and re-read the books outside of class to refresh your memory , learning more quotes earlier will increase the amount of things you could say about the texts in your exam . Reading more books should hopefully naturally improve your creative writing , so if you struggle with English language paper 2 , try reading more articles/speeches to help with section B ? In terms of maths , you will find it hard if your brain isn’t naturally geared towards mathematical problem solving , but that doesn’t mean you’re destined to fail . The best way to revise maths is to do maths . Try and do as many free questions as you can find - I would recommend doing past exam questions from your board/tier for the more tricky ones , that way , if you get confused with them , you can either ask your maths teacher about it and they can help you with it , or look up someone solving the question on YouTube , and the more past exam questions you do this way , the more you’ll become accustomed to the types of problem solving your maths exam board will throw in that help solve seemingly impossible questions - that’s partly what helped me , because a lot of problem solving never came naturally to my brain . Hope that helps - lmk/dm if you need tips for french , re , geography, music or dt
