Our courses are designed to be flexible so learners can adapt the lessons according to their needs or learning style.
However, we tend to recommend listening to one or two Interactive Audio lessons and then one or two Language & Culture lessons as the lessons often relate to each other. Once you are relatively comfortable with the language, you can try using the games to solidify your learning and get more practice. As you work through the course, try doing a few Survival Kit lessons - these are not in any particular order however they contain bonus lessons with important vocabulary that you will find useful throughout the course like colors, days of the week, etc.
For extra practice, check out the "Practice" tab in the Interactive Audio lessons. You can also rate all your lessons using the My Level feature - for more information on how to use this, please watch the TOUR video in any lesson.
I hope that helps!
