Practice, with a little more purpose.
Work without a countdown. Try the model, use a hint, then read the explanation. Checkpoints and practice records stay on your device. Teaching tools create shareable activity playlists and printable worksheets with answer keys.
These are original practice activities, not an accredited course or a secure assessment. Difficulty labels are editorial, not formal grade alignment.
