Hi
Today, I studied OPD, lesson 5. But not it’s book. I Studied with windows OPD software. It’s very useful and funny. Please guide me about studing OPD. OPD studing entail a long time working for each lesson. Should I start next lesson of level 1 when I finish studing OPD part of previous lesson?
Thank you

yes, you’re right
OPD takes a lot of time, you can continue your lessons in American course and play OPD games in its software everyday
Thank you for explanation
