I write summaries and use only the information in my summary to answer practice questions (like an open book test). I also shorten my summaries every so often, sometimes completely re-write them with additional research and then attempt more questions. Sometimes I attempt the question more than once making sure I word the introduction differently each time, that way when I'm in the exam room I don't have to quickly think up an intro on the spot (I find the introduction is the hardest part), I can use something I've planned
