Who this course is for
Instructor: Kesara Bandaragoda — Founder of Geeks Around Globe | CEO at BrandFactory | AI-Native Systems & Media
Beginners and busy professionals who want dependable results from AI: people who have tried a chatbot and want a method, and anyone whose AI-assisted work has to stand up to scrutiny. No technical background needed.
Prerequisites
- Access to at least one AI assistant. A free tier is enough.
- About 15 minutes a day for four weeks, or more if you prefer to go faster.
Why this course exists
Why this course exists
Most people meet AI the same way: a few impressive answers, a few confident mistakes, and no reliable way to tell them apart. This programme is that way, taught one day at a time. It follows the working rule of the Geeks Around Globe newsroom: trace every claim to a source, and check what AI produces before it goes anywhere. Each week ends with something you keep, from a prompt library to a verified research brief and your own AI operating system.
What you can check
- 28 lessons of about eight minutes, each with a practical exercise and three quick checks that explain every answer.
- A final assessment drawn from a 48-question bank: 20 questions an attempt, 80% to pass, up to three attempts a day.
- Every certificate carries a credential ID and a QR code that opens its live record on geeksaroundglobe.com.
- A private certificate of completion, not an accredited academic credential. The certificate says so itself.
