Here at SCM we schedule:
6 Picture Portfolio studies (10 minutes per week =12 hrs)
6 Music with the Master studies (10 minutes per week = 12 hrs)
2 terms of art instruction from Creating a Masterpiece & 4 terms of Handicrafts DVDs (20 minutes per week = 24 hrs)
Hymn Study for the entire 2 years (10 minutes per week = 12 hours)
Sometimes those lessons will run a bit longer but the numbers above a solid place to begin.
