At a glance, you're Venus. Venus is in fall. You don't like this situation at all.
I'm not sure which house to use for the course. Higher education is ninth house, but this isn't the same as normal higher education, by a long shot. Third house is lower (elementary through high school) education, and close to home instead of away. But since horary meanings predate online courses by many centuries, we don't exactly have a house for that.
I think, all things considered, the sixth is probably most accurate. That's the house of apprenticeship. An astrology course isn't exactly like traditional apprenticeship either, but it's closer to that than to university or K-12 education. And what do we have here: Venus in the sixth, in fall, with the sixth house belonging to Virgo, Venus's detriment sign. That's double testimony to you not liking this.
Venus's sign of Libra is intercepted in the sixth, with house ruler Mercury placed there. I take that to mean you like (Venus likes Libra, and by extension, likes any planet placed in Libra) the subject at the core, but you don't like the package it comes in. Since Venus is in Scorpio, not Libra, the part you like is probably going to be inaccessible to you through this course.
That doesn't necessarily mean a different astrology course wouldn't suit you, but that would be a whole separate question.
