I don't know if this post is related to Academic Guidance, but it seems to fit here. So the question is simple, how much do you work daily/weekly/monthly? (choose what period of time you like). How long does it take for you to finish a book of...say 600 pages. (I know that different books take a different amount of time to complete, some being easier than others, but let's just say a standard undergraduate textbook on mechanics).
