Go over the topics that you have covered on your own since the last classroom lesson. Think about what you have learned and what you can do with what you’ve learned. For example, order something in a restaurant or carry on small talk with a business acquaintance. In the lesson, you’ll go over these topics in discussions and role plays.
Of course, you’ll benefit most from the lesson if you actively practice the vocabulary and grammar in advance using the e-learning program and have, ideally, already had the opportunity to apply it.
