Sorry if this is a poor question, but I was wondering if renshuu automatically suggests adopting a new schedule once a certain level of mastery or introduction to terms has been reached. For example, most of my schedules now are the Beginner ones, so will there be a point when I get far enough with Beginner Kanji (N5) that renshuu might suggest moving on to the N4 Kanji in the Pre-intermediate schedule? Or is this all at my own discretion as to when I add these new schedules?
Yes, renshuu does! Once you've learned everything in a schedule, renshuu will let you know and suggest moving on to the next schedule. You can choose to continue studying that level or move on when you're ready.
The main trigger point is when you've studied everything in a schedule at least once, or in other words, there are no more materials for you to be introduced to. At this point, it'll let you know.
That being said, there is no rush to get into new materials - check out this discussion on the topic: https://www.renshuu.org/forums...
