Brilliant does not offer a feature to reset an entire course at once, but you can reset your progress from a specific point onward.
Resetting an individual lesson
You can reset individual lessons from the course page by clicking the Redo icon or the Review button, depending on the course structure.

Resetting a level (web)
On web, you can also reset progress on a level-by-level basis. Tap a level on the course page and select Reset progress to here. This erases your progress in that level and every level after it in the course — it can't be undone, so use it when you want a genuine do-over from a certain point rather than resetting one lesson at a time.
If you have further questions or need assistance, feel free to contact our support team at support@brilliant.org.
