You have lifetime access to this course so you can’t fall behind in this course. There is no specific time you need to login to access the course content.
With that said, to fully take advantage of the Eriksdotter Support System which includes the Peer Love forums where you receive support from and engage with fellow students in the course or the Live Group Coaching Video Calls, it’s helpful if you do the modules as they are released. Maybe that’s something you can revisit during next year’s live launch since you have unlimited access.
