Thinking of coming back

You should consider using @rfindley’s Self-study script to see determine where you should draw the line with regard to your reset. It’s essentially a quiz that you can do for each respective level. Once you reach a point where you feel things are okay, you can reset to that point. That way you’re not shooting yourself in the foot by resetting too far back.

What are you learning goals? Reading, writing, speaking, listening? I think your trajectory would differ based on what area(s) you’re trying to attain fluency in.
