Polygon examination
Quest, timer test and open task
This is the final test for the whole of Chapter 9. The tasks are similar to those found at the EEG and the EGE.
The examination consists of three phases: Quest scenarios (8 questions), a bank test (15 questions, timer 15 minutes) and developed tasks with formula.
