English

For literature, the best way to prepare is by learning a set of useful and valuable quotations for each character and each theme for the books you're studying. Learn multiple sets of analysis for each quotation too, and make sure you are able to pick out literary techniques and devices (metaphors, alliteration, similes, etc. and also lesser known ones to impress your examiners). When you learn your quotations, make an essay plan for each theme and each character, so you will be prepared regardless of what the questions are in the exam. You can also write full essays and preferably get feedback on them so you know how to improve, but since it's pretty time-consuming, you don't need to do too many of them; do more essay plans than full essays, so that you get an opportunity to practise every topic. Of course everyone plans essays differently but to give you a general outline, you should write what your 3-4 paragraphs would be about and write down quotations and analysis for each paragraph, and follow it up by mentioning context for each paragraph.

For language, the best thing you can do is practise, so most of your time should be spent on practice, once you've learnt all the question types and once you know what to expect from each paper. Work on your ability to analyse and recognise language techniques, and make sure you're able to explain what the effects of using these language techniques are. For the writing section of language, here are the main things you can do:
1. Know how to effectively plan your writing
2. Learn impressive vocabulary to use (but don't overuse complex words and only use them where you're confident on their meaning)
3. Read model answers online to see what they've done well and how you can improve your writing
4. Know how to write different types of non-fiction eg. letters, magazines, etc. and know how they differ
5. Do lots of practice so that different topics/prompts won't throw you off and to make sure you're incorporating all the right things.

Some useful YouTube channels include Mr Everything English, Mr Bruff, Stacey Reay, Mr Salles and First Rate Tutors. Make sure to read examiner reports as these are basically free help from the examiners themselves - they are telling you exactly what they want to see and what they don't. If you have any more questions feel free to ask, good luck!
