New Lessons starting June 21st

Week 1 Which tone was that again? (ele) Week 2 World Cup and Diamonds (ele) Week 3 Security Check in the Subway (ele) Week 4 A New Jug for the Water Cooler (ele) I plan to master each lesson and do all exercises and test. Is this ok if we do one lesson per week. I think this will work best with my schedule.
