Does anyone have a quick way to solve this??? Takes me FOREVER!

you need to extend the list of possible inequalities: k<j, f<j
I. k < h --> k<j and h<j not defined
II. f < g --> since g<j and f<j not defined
III. k < g --> this is given

This one drops out in a minute if you use LSAT logic games tools


g--->k

j--->h

j--->g

h--->f

put them together you get
h--->f
/
/
j
\
\
g--->k


with this diagram you must start with j and you have to keep the g--->k and h---f relationships, but there are no rules about the relationships between the two legs of the diagram.
