In brief. This course is for employees and professionals who use Google Gemini, from free web access to Gemini for Google Workspace in business settings. It starts from the fundamentals and climbs to expert level across four milestones: Beginner, Intermediate, Advanced, Expert.
Each lesson takes fifteen to twenty minutes and follows the same rigorous learning cycle. You begin with an unaided cold attempt to assess your instinctive approach. You then explore the core concept, illustrated by a clear diagram, and study an example contrasting weak and effective prompts using the Google PTCF method.
You then practice hands-on, study a realistic failure mode, and validate your understanding through a three-question quiz with detailed rationale. Finally, you submit your proof of mastery to enrich your portfolio and unlock the level badge.
