Pick up where you left off

Keep the next question waiting.

Save an active generated practice session before closing the tab. Load it later to resume the same question, entered answers, attempt counts and viewed steps.

Save deliberately

Save generated session keeps one snapshot in this browser. Later answers are not saved automatically. Replacing a saved session asks first; download its saved data if you need the earlier version. Loading is a separate action and asks before replacing active practice.

Take a backup with you

Download current session backup creates a portable JSON file within 100 KB. It contains the repeat code, topic, unit system, question count, current question and answer state. Restoring changes the active session; it does not overwrite browser storage until you choose Save.

Questions and worked answers are regenerated from versioned settings. The importer validates the state and checks current feedback against the regenerated answer. A backup is still a user-editable personal record, not an authenticated exam result.

Keep other progress separate

Generated sessions use their own browser storage. The sixteen original drills retain their separate solved identifiers. A reading-copy session report is still text and cannot be used as a restore file.

Two tabs and unreadable data

A save refuses to overwrite a session changed by another tab since it was read. Download your current backup before loading the newer saved one. If stored data is unreadable, download it before choosing to replace or delete it. Clearing saved generated practice leaves the active session and original-drill progress in place.

Browser data can be cleared or evicted. Keep a downloaded copy where you can find it. Backups include your entered answers and practice state; no cloud account or automatic synchronization is provided.
