How to play Grammar App

1. Open Learn and pick a book: Basic Grammar (10 topics), Punctuation Rules (12 topics) or Writing Rules (3 topics).
2. Each topic is a handful of short pages with examples. Quick checks pop up as you read so you can try the rule straight away.
3. Go to Test for a 25-question Assessment, a Mastery test of harder mixed questions, or a topic test on just what you read.
4. Every answer comes with the rule behind it, so a wrong answer still teaches something.
5. Play Word Drop: words fall one at a time — sort each into the right part-of-speech bin before it lands. Progress shows what to revisit.
