The content seems well-condensed, but the document editing feels so haphazard that it's difficult to read... I wish things like tables being cut off or just one or two lines spilling over to the next page could be fixed so that it's easier to read at a glance, even if it means leaving empty space and wasting paper. Right now, it just feels like a set of handwritten lecture notes passed down in college. I wonder if this is really worth paying over 30,000 won for.
