We've had some queries regarding basedata and components with 'time allowed' set to zero.
The reason for this is that some question papers have been split into multiple components – eg section A is a component, section B is a component, but sections A and B are designed to be taken as one exam in a single exam slot.
The overall exam has a time (eg 90 minutes) but the components (or sections) that make up the exam don’t have specific time allocations. It’s therefore entirely up to the student how much time they spend on each component. To find the duration of an exam please check the exam timetables.
