My method is probably the most retarded out there, so I'll share it with you guys
15 minutes reading time:
5 minutes brainstorming and planning for all four TR prompts, deciding which one I can write the best with
10 minutes reading and analysing the article/(s), deciding how I'll break down the piece into paragraphs to write about
Start:
10 minutes planning for everything, the "shotgun" approach. Jot down all my ideas onto 3 separate pages - one for each section
40 minutes or so writing the first half of my LA (section C). Meanwhile, I'll be thinking about TR and C&P prompts and jotting any other ideas I have about them on my planning sheets
50 minutes write my C&P (section B)
45 minutes or so writing my TR (section A), everything except the conclusion
30 minutes finish LA then go back reread my TR essay and write the conclusion
Last 5 minutes (if that) stress about why I did my essays in such a stupid order (done the same thing for both practise exams so far) and try to pick up as many of my mistakes as I can

Sometimes I even change halfway between essays... please don't bag me. Sheets are always everywhere when I write LOL
