Waterloo Math faculty conditional

So one of the conditionals is: “You must achieve a minimum final average of 80% in any 12 U English, 12 U Advanced Functions (MHF4U), and 12 U Calculus and Vectors (MCV4U).”

Does this mean the combined average of the three prerequisite courses? Or does it mean you must get a final grade of 80% in each prerequisite? If someone could clarify that would be great!
