I may be wrong but I think there were (are?) differences in terminology between Commonwealth countries and the US
I believe "Course" and "Heading" meant the same thing in Commonwealth countries (eg the instruction "take up a course of 340" meant turn onto a heading of 340). We tend these days to not use the term Course (at least I don't), rather refer to Tracks and Headings (and Tracks Made Good, Track Errors etc).
In the US I believe that what we call "Track" is referred to as "Course". I think this has confused more than one person early in their training when they read the US instructions on whizz wheels. Well at least one person... not mentioning any names of course
My navigation and altimetry (where not provided by electronic gee-whizzery) is typically done by approximate rules of thumb so I wouldn't take what I say as gospel on any of that though!
