All the content on this site comes from one place in the code: the SITE_DATA object near the top of the <script> section in this file. Open index.html in any text editor (Notepad, VS Code, etc.) to edit it.

To add an image exercise (a scanned worksheet, a screenshot, a design sample):

1. Put your image file in a folder next to this website, e.g. exercises/msoffice/word-resume.jpg
2. In SITE_DATA, find the right subject and add a new entry:
   { title: "Format a resume", unit: "Word", type: "image", file: "exercises/msoffice/word-resume.jpg" }

To add a text exercise (typed instructions):

1. Add an entry with type: "text" and write the exercise directly inside text: "..."

The unit field (e.g. "Word", "Excel", "2D Drafting") controls the filter buttons above the grid — group exercises however suits your syllabus.

Once edited, re-upload index.html (and your exercises folder) to wherever you're hosting the site, or share the folder directly with students.
