Here is what I've gathered and I've been getting quite good marks. I try to follow what I did for English and PCRE GCSe's which was a mnemonic for every question type so that it prompted me to think in a certain way.
Obviously when approaching apply question you want to find quotes from the items, then link to your knowledge. I use keyboard so I can use a table in word, but you can probably just write out the basic ideas onto the exam paper. The I usually use Statement, Item/theorist, theorist/Item, Effect(societal topic)/Application(method), Conclusion (just a mini one for the paragraph). It's effectively PEEL but labelled so I remember what to do and when.
20 markers and 30 markers are the same, equal for and against was what I was taught for PCRE, I reckon it applies. 4 points total vs 6 total for 30 marks. Always add a conclusion, if you actually have the foresight an introduction is good too. Maybe just leave a big gap before you start your exam, and then write in an introduction at the end.
10 markers are the same structure but without any opinions, as they are just explaining points. I use Statement, Evidence, Effect, and Conclusion. Because we are SEEC'ing the truth

Finally it should be organised and consistent. But if you are in the middle of a sentence explaining impact, and suddenly you remember more content that directly corresponds with your statement, then you should just add it.
