This demo course is built with the same content pipeline used for every BlitzGrok course. Open any topic to see how reading material, media and practice fit together.

What you will see

• Markdown-rich topic pages with headings, lists, tables and code
• Multiple-choice questions with hints and worked explanations
• Parameterised questions that generate a fresh variant every attempt
• Images, comic strips, embedded YouTube video and sandboxed applets
• LaTeX formulas, a plotted graph, and figures drawn by code for each attempt
• Letter-writing practice on a canvas and listen-and-repeat pronunciation drills
• How modules, topics and FAQs are organised for learners and search engines

Everything here was loaded from a handful of JSON files plus a media folder. Replace the content and you have your own course.
