To prepare for this lesson, review the official brief's submission rules and prepare a sample zipped project folder demonstrating correct structure, including anonymised data and offline-accessible files, to model best practices for students. Facilitate by guiding learners through each step interactively—start with a quick discussion on real-world consequences of submission errors, like GDPR breaches in professional settings, to boost motivation and underscore the stakes. Emphasise key concepts such as precise folder organisation (Report with local index.html, Artefact with clearly named code), virus scanning, offline testing on disconnected devices, and completing the signed Authentication Form P.2, while highlighting pitfalls like online-hosted content or missing files that lead to penalties. Engage students by having them self-audit their projects in pairs, troubleshooting issues like unopenable links collaboratively, and differentiate for varying needs by providing templates for non-standard code or extra time for data anonymisation checks. Wrap up with the submission checklist to ensure backups are retained until assessment ends, celebrating completion to reinforce diligence and compliance.
