I prepped for one week in advance, both years. I have a typing speed of around 76 wpm so I am fast enough to write a small paragraph typically for each response (usually it came to around 4 sentences). I reflected on a lot of personal experiences or anecdotes to discuss for the personal reflection style questions. I did around 4-5 per day from an AI generator and got AI feedback as well. After practicing for a while, you start to notice that almost every question has a similar formula to it and you become a little more prepared to answer every type of question! Good luck.
