Keyboard Harmony Exam?

I can't speak from personal experience, because i prepare my students for written theory exams and not these ones, it's just what i'm more familiar and comfortable with. i have a friend though who's been teaching for probably 30 yrs, and quite experienced with theory, and she prefers these exams to the written ones. according to her, the students find these exams easier than the written ones. to be encouraging though, it's been my experience that when a student clearly cares as much about how well they do as you do, then they care enough to prepare themselves well for examinations. to give you a bit of general advice though, played exams tend to go better when you're relaxed through the process, so try not to work yourself up too much:) good luck!
