What is the best way to plan my EPQ?

I found a helpful way to plan my EPQ was to write down the points I wanted to make for each paragraph on a word document in a list. I would then write a sublist under each point of all the evidence I wanted to use in that paragraph. I then transferred this to flashcards, each flashcard containing something I wanted to write in the paragraph. I would have about 5-10 flashcards per paragraph (I attached them together so I would know the order and I wouldn't lose them). I also labelled each flashcard with a number, this number matched the paper I was referring to in that evidence. So I had 25 papers/journals I had used for evidence and had labelled these accordingly, if I were to use evidence from paper 5 in a paragraph, I would put the number five in the corner of the flashcard
