Field notes
The workflow depends on the site's own printable A–E forms: print at 100% / Actual Size, scan at 300 DPI, put the completed key on page one, and keep student sheets in the same PDF. The homepage says a free account adds basic score statistics, while a one-time $10 Premium account adds CSV exports and history for the latest 50 scans. It also cautions users not to include identifying details in PDF filenames used for history.
