You can delete only exam pools that do not have any exams assigned to them or any their sub-pools. If you want to delete an exam pool that contains exams, delete the exams first, or re-assign them to alternative exam pools. You can then delete the empty pool. When you delete an exam pool, its sub-pools are also deleted.
Administrators with unrestricted access to the Exam Utilities feature in System Roles (Manage Features > Exam Manager Features) can delete exam pools.
