I'm experimenting with allowing lesson requests within 12 hours, instead of 24 hours. I will see if this makes it more convenient for students. This is fine for lessons for which I don't need to prepare special materials. If you do need materials prepared, please request the lesson farther in advance. In the case of the kid's English lesson, please let me know at least 48 hours in advance if possible, as I would need time to customize the lesson for the child's age, etc.
