you're using the pearson edexcel textbooks for maths right? if so, do all the question labelled E/P -- they're the exam styled/past paper questions. practice little and often and try to do the question after covering them in class. ask for help if you need!! if your teacher's way of explaining doesn't make sense, there are so many youtube videos that can probably put it differently in a way that makes sense. in terms of other resources:
- physics and maths tutor
- dr frost
- maths genie
honestly though, i think the textbook itself is sufficient. there are more than enough questions to do for the duration of the course and maybe start past papers after you've finished everything in your second year. also, get familiar with the functions of your calculator -- if you're not doing a non-calculator paper, take full advantage of everything you can do with it. there should be videos on youtube explaining all the functions if you're not taught in class.
for english, get used to the mark-scheme. if i'm not mistaken, 50% of the comparative essay is context. learn your context!! i think it would be a good idea to use flashcards -- physical ones you can hold would be best. learn both as much context and critics as you can and use active recall, so do a little everyday so by the end of the course you'll be super familiar with it. don't forget that for context, you can also mention things that were inspired by the texts, e.g. film adaptations. just don't get them mixed up with the actual text. just get familiar with your assessment objectives in general because it's how you gain marks, even if you have amazing understanding you can't score high without hitting the mark scheme. that also applies to other essays such as the unseen one which requires heavy analysis of language and form etc.
other things:
- read around your subject (books, essays, even watching videos of the author's life)
- use quizlet -- there are a lot of resources made already. i like to find critics on there and then search the quote up on google so i know which essay or book it's from.
- look through past paper questions and plan them -- get a grasp of the similarities in all of the questions and revise your quotations based on that
- again, ask your teachers!! ask them for feedback, ask them if you're not sure how to structure something, ask them for recommended resources. they're there to help you.
most of all, enjoy it! english is so much about just enjoying the texts you study and if you're genuinely interested in what you're revising, it'll make studying it so much easier. don't put too much pressure on yourself, because that really doesn't help anyone. your grades can be really affected by how you're doing mentally, so if you're not feeling great, i strongly encourage you to talk to someone about it. you don't have to have the worst problems in the world to make these worries and feelings valid -- so please do reach out if you're feeling stressed or just low. i think that's all i have to say for now, so take care and best of luck for your a levels!!
