Can I study multiple levels at once?
Lessons are designed to be studied in order, since each level builds on knowledge from the previous one. Focusing on a single level at a time helps you develop a strong foundation and prevents gaps that could make later material harder to understand.
If you want to change levels, you can reset your progress and switch to a different chapter or JLPT level at any time. This allows you to adjust your path based on your experience while keeping your study organized and effective.
