Any direction would be great.

Please post a more complete example. With only the goals you state,
SWI Prolog responds:

?- Goal =.. [prerequisite, _, Course], nl, write('Goal: '),
write(Goal), nl, nl, call(Goal).

Goal: prerequisite(_G173, _G176)

ERROR: call/1: Undefined procedure: prerequisite/2
