Most testing courses teach you the vocabulary. This one makes you make the decisions. You will not find a glossary being read aloud here. Every technique in this course arrives attached to a decision somebody has to make with too little information and not enough time — which is what the job actually is.
The whole course runs on one product. Sparrow is a food delivery app with thirteen written rules, and those rules behave the way real requirements behave: two of them contradict each other, one says nothing about the case that breaks it, and another was changed in the app and never written down. Every technique you learn lands on those same rules, so nothing is a toy example that only works because it was built to work.
The course is built in pairs. One lecture teaches the idea with no product in it at all. The next lecture, four minutes later, runs that same idea on Sparrow end to end. Theory and practice never get mixed inside one lecture, because that is how people end up recognising a technique without being able to use one.
