I'm currently close to the end of Course 1 of JFZ and the thought occurred to me, how do people revise what they have learnt. I use anki as flip cards for words and some sentence/grammar structures but am keen to hear how people revise their learning from the previous chapters, how often you go back to revise past material and fundamentally 'how' you revise (techniques). Do you go back and write out sentences, do you develop your own sentences, do you write out grammar rules until they stick in your head? do you use revision schedules and if so do you have any resources you rely on to support the revision session?
I can learn concepts from the book, I can read the chapters etc but revision feels a bit like a dark art for me right now and I'm worried I forget what I know because I don't have an effective revision system.
