◆ Test yourself
Every question tells you at once whether you're right — and why — then scores you at the end. The tiers below widen as you go down: one section of a branch, then a whole branch, then the whole subject at once.
One per section of the curriculum. Each question connects two or more concepts from inside that section, so these test whether the ideas fit together — something taking the lessons one at a time never asks you. (Every individual concept lesson also ends with its own single question.)
A mixed test across one entire branch of philosophy, drawn from every concept in it. Clear all five to master the map.
The widest tier. Every question here draws on at least two different branches, so none can be passed by revising a single lesson — these test whether you can connect what you've read across the whole subject.
