over a week ago, my notes went missing. i looked but assumed they'd turn up and they didn't. i had a proper look over last week but they've vanished into thin air.these are the notes on paper 2, which i have a mock for at the end of February. i don't know the content well, so those notes would have been useful- what should i do? is it worth copying out all the notes again? i could focus on just exam questions, but i dont even /know/ the content in the first place. i have borrowed another textbook so i still have access to resources, however detailed diagrams and explanations lack in my book (AQA) that my teacher had ran through in study sessions.i also have a test coming up this thursday, the notes i have for half of the topic- the other half are lost along with my book. what should i do?
