Question for the small FBO instructors, out there:
How do you track your student pilot lesson progress? We have several instructors, one airplane, and handing folks back and forth due to line flying can be frustrating.

I've tried the ASA folders, they seem to be overkill in some areas and weak in others. I've tried free form entries in student binders, and that works pretty well. Takes a lot of time, though. I'm still looking for the right answer.

What are you small FBO CFI's doing for ground lesson and flight lesson tracking?

Thank you!
