LEARNING FAQ
Learn for understanding, not just the certificate
The certificate is the result of the work you put in. Take your time, stay curious, and use the course to build knowledge you can apply with confidence.
Why should I watch the videos on this platform?
The videos are hosted on YouTube, but you must watch them here, inside the course. You need to watch at least 80% of each lesson before it can be marked complete. The platform records the sections you actually play, so skipping forward does not count. Watching the same video directly on YouTube does not update your course progress or unlock the certificate pathway.
Can I watch a lesson more than once?
Absolutely—and we encourage it. Rewatch difficult sections, pause when you need to think, and return to completed lessons whenever you want. Repetition is often where understanding becomes lasting knowledge.
How can I get more from each lesson?
Take notes in your own words, write down unfamiliar terms, and pause to connect new ideas with what you already know. After each video, try to explain the main points without looking at your notes. If something is unclear, watch that part again before moving on.
Should I focus on completing the course quickly?
No. The goal is to understand and retain the content, not simply to reach the certificate. The final assessment checks your knowledge, while the certificate recognises what you have learned. Move at a pace that lets you genuinely understand each lesson.
