How and what to submit

We'll put up the submission link soon, but here's what you need to prepare!

You can download this submission template (PowerPoint file) to get started.

  • Slides or Document: Include these: (1) Your name, school, and competition serial number; (2) Title and description of your project, how it relates to the theme, and any awards you are aiming for; (3) What you learned; (4) The items below. We will put up a downloadable template for this soon, but you are free to get started.

  • Photos: Take between 2–5 photos of your project in action, or how you made it! Be sure to show off the best view of your project. Include these in your document.

  • Code: Take a screenshot of your code. In MakeCode, right-click an empty code area, and select Snapshot. Next, click on the Share button at the top left, Publish your project, and copy the link. Include these in your document. If you're working in syntax-based code like Python, you can just paste the code in the document, or paste a link to a public Gist, or use a hastebin like code.tk.sg.

  • Video: Take a video introducing your project! The video should be between 15 seconds and 1 minute long. TikTok-style music videos encouraged, but no need to dance. Upload it to YouTube, set it to public or unlisted, and include a link in your document.
