Examination action verbs

As with all examinations, it is important to know what the examiners require. The IBO releases a list of key words and what they mean when referring to exam questions.

For example the word "Draw" is taken to mean "represent by a series of pencil lines and labels (unless specifically told not to do so)" This leaves the students clear as to the actual requirements of the questions. A full list of these so-called action verbs can be found here
