Study Chapter 01 →How to study with this library
- Read the lesson and note the rule in your own words.
- Compare the correct examples with the common mistakes.
- Complete the practice tasks before checking the answers.
- Use the linked quiz to test recall, then revisit the rule behind each mistake.
Learning principle: memorising an answer is not the same as understanding a rule. Each chapter is intended to explain the pattern and show how to apply it in a new sentence.
The chapters are being developed and reviewed progressively. The roadmap below shows the planned sequence; a chapter is marked available only when its lesson page has been published.
