A reason to come back.

Read a field note, reconstruct objects and signals, then return to the note. Each exercise has its own difficulty level. Two consistent results can move one path forward while another stays where it is.

Your goal is a more demanding task, or greater accuracy at the same level. Taking a day off doesn’t reset that progress. Sign in to keep a notebook across devices; guest results stay on this browser for seven days.
