At the end of each module of study (typically, three modules per course), you will have an exam of between 20 and 90 minutes duration. This will depend on the standard and on the scope of certification concerned.
All ISO certification examinations are of the ‘open book’ type.  You may keep a copy of the standard with you during the exam. You may also use any notes or reference books you may have.
All answers are submitted on-screen in response to multiple-choice, matching, true-false and similar types of questions.
