From an error to your next exercise
Find topics in your writing
A checked text gives you corrections and explanations. Grammar topics connect those corrections to something you can work on.
Revisit your own examples
Saved examples help you see how a rule applies to the sentences you actually wrote. Repeated mistakes give you a reason to revisit a topic.
Practise one topic
Choose a topic and generate a focused set of exercises. Review the answers and assess how confidently you can use the rule.
Return to your practice
Your practice history keeps previous sessions available. Self-assessment helps you decide what deserves another round.

What does grammar progress mean?
Your history records practice, and your self-assessment reflects how confident you feel with a rule. It is a learning aid, not a measured percentage of English grammar you know.
