How the two differ

The exhibition is 950 words about three objects and one prompt, marked internally, and it asks how TOK shows up in the world around you. The essay is 1,600 words on one of the six prescribed titles, marked externally, and it asks you to argue about knowledge itself using areas of knowledge the title names. The essay carries two thirds of the grade.
