Are There C1+ Level Units?
We have many more B1/B2 Units in progress, but currently we don’t have plans to create C1 Units. (We have some ideas in mind for additional advanced content, though.)
By the time you get to that stage, the format of learning at the sentence level is not ideal. Instead, you should be at the conversation level and engaging in more extended use of the language. In other words, doing fill in the blanks, multiple choice, etc., would be too easy. Much of your learning will happen within your real-life interactions, and with regular native-level content.
Instead, we normally recommend that advanced users spend most of their time with the Shorties, Podcasts, and Videos, and to use them as inspiration for exploring the language further. For example, instead of just listening to the episode and doing the quiz, you could write or retell what happened in the episode to someone else in your own words. Or write/tell your own version of what “part 2” would sound like. This gives you practice with more creative / free-form use of the language.
Many of our advanced members also use the Smart Review flash cards (and the Listen & Speak audio review) regularly as a way to keep their skills fresh, to improve their speed, to sharpen their pronunciation, and to expand their vocabulary and “go-to” expressions.
We are looking into other advanced activity types and we’re always open to suggestions for topics and features! If you're around the C1 level, at this stage, your gaps in knowledge are often very specific to your own experiences. Let us know which areas you need to practice more and which topics would be helpful for you. (You may also find this useful for exploring our resources by topic: Site Index)
