Just looked at the counterpoint syllabus listing. I've studied species counterpoint in uni but never taken the RCM counterpoint exam.
The subject matter appears more towards applied counterpoint, fugal studies, and baroque dance forms. A good majority of the items seem to focus on fugue writing techniques and analysis of such techniques. As it stands IMO the prescribed title of "counterpoint" is misleading and a bit inaccurate.
You may be better off searching for books on fugue writing and Baroque dance. There is a list of books at the back of the syllabus but somehow a couple of them do not seem congruent with what the syllabus is stipulating for the exam. Keep in mind when looking for books species counterpoint is quite different from the applied counterpoint this syllabus setting out.
If you at all enjoy learning the "counterpoint" curriculum in this syllabus, I suggest you do take on species counterpoint.
