I have to write a 10-20 pg research paper on a topic in human physiology using medical journals primarily as sources. I have an entire 7 days to focus just on this task. Does this sound feasible to come out with a respectable looking paper? Of course it depends on what topic I choose to research, any suggestions would be extremely helpful thanks. This is for a human phys course.
