Who is the Code Review poster for?
Code Review belongs to the Computing section rather than to a school year, because computing is not something one grade owns. Anyone learning tools can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Code Review poster?
Review the design first. Style comments on a wrong approach waste everyone's time. A wall chart earns its place by being glanceable from where the work is happening, so Code Review belongs on the wall where that computing work actually happens, within glancing distance, rather than filed away.
What other posters go with Code Review?
Debugging Method, Docker Basics and Writing a Dockerfile sit alongside Code Review in the Computing section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Debugging MethodDocker BasicsWriting a Dockerfile
Is the Code Review poster free to download and print?
Yes. Code Review downloads as a free PDF with no account, no email and no watermark, like everything else in the Computing section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Code Review poster print at?
Code Review is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Code Review loses nothing.Printing guide
