In Lower Intermediate L6 lesson 14 or 15, you asked how often do we listen to the lessons, where, etc. I live in Singapore, and walk to work each day. It's a 15 min walk which gives me a perfect opportunity to get 30 min/day 5x a week. Initially I listened just one time to the lesson, but around the 8th or 9th lesson I found myself listening to it two or three times. Now I just listen until I fully understand everything that is said -- both in the lesson, and in the commentary between the three of you. That usually takes 3x, but sometimes 4, 5 or even more.
Ganbarimasu!
