# Original printable PDFs

Six one-page PDFs: completely blank A4/Letter portrait paper, a monthly habit tracker in A4/Letter landscape, and a generic 50-question A-D answer sheet in A4/Letter portrait. Tracker has nine habit rows and31day columns. Blank files have no visible marks or selectable text.

Download the PDF for printing. PNG files are 96DPI previews rendered from the actual PDF with Poppler, not design mockups. Print the matching paper size at Actual size/100%; choose landscape for the tracker. Printer margins vary. The generic answer sheet is for manual checking and is not calibrated for an OMR system.
