What you can do at C1

  • Speak easily, without looking for words.
  • Write well-organized texts about difficult topics.
  • Change your style: formal for a report, relaxed with friends.

Although the new design looks simpler, it might cause problems when we have more users.

Grammar at C1

  • Future perfect: By next year, I will have finished the app.
  • Perfect continuous tenses: I have been coding for three hours.
  • Formal linking words: however, nevertheless, therefore, despite.
  • Mixed if sentences: If I had studied harder, I would be at C1 now.
