Writing dense exam cheatsheets: telegraphic procedures beat prose

When a student asks for a cram sheet that is filled and compressed: (1) drop exam rules/logistics, headers and source notes, they waste space; (2) organize around question types as "Q: <what they ask> -> steps" procedures plus a short worked example from past solutions; (3) give definitions in telegraphic style (no articles, arrows, + / - for pros/cons, small tables for state machines and policy matrices); (4) mark material that does not come from the course materials as (maybe) so the student knows what is unverified. Rendering: pandoc + headless Chrome with CSS column-count:4 at ~5.2pt on letter paper fits about 2,000 words on one page. Check the result with pdftoppm and look at the PNG, because the page count alone does not show whether the page is actually filled.
