As you journey through your course, we’ll automatically add grammar topics to your Grammar Review. After completing a grammar lesson, you’ll be able to revisit the topic and practice at your own pace in the Review 
section.
If you’re a Premium subscriber, you can unlock grammar topics directly from the Review section. Simply go to the Grammar tab, select the desired section or topic, then select Learn grammar. This will take you to the lesson to unlock your chosen topic. Once completed, the topic will be marked as learned and assigned a strength level—Needs practice (Red), Improving (Yellow), Strong (Blue) or Mastered (Green).
