# Grammar Insights

> See your most common mistake types and how much of each CEFR grammar level you've mastered — across all your lessons.

**Grammar Insights** (web app, marked *Beta*) zooms out from a single lesson to show patterns across **all** your lessons. It has **Mistakes** and **Grammar** tabs.

## Mistakes

* **Total Mistakes**, **Mistakes/Hour**, **Total Hours** of learning, and the number of mistake **Categories**.
* **Mistakes by Category** — your distribution across grammar categories (Articles, Tense, Verb Form, Word Order, Prepositions, Determiners…). Click any category to see the breakdown.

This tells you, at a glance, what to focus on — usually your biggest one or two categories.

<Tip>
  Use this before a lesson: tell your teacher which category you want to focus on (e.g. "articles" or "past tenses"), and bring it up in your AI practice too.
