NEBOSH have recently announced the launch of a new online open book exam. This information is therefore no longer applicable. You can find out more about by reading the new learner guide.
NEBOSH updated its most popular health and safety qualification the NEBOSH General Certificate in Occupational Health & Safety on 4 September 2019. One big change is the assessment framework. It is a positive change because the number of assessments/exams has been reduced and it is a bigger practical element using management models.
The first thing to note is not to worry about the exam and assessment. You will have plenty of help and guidance throughout your course. A good course provider will also offer plenty of practice of exam and assignment questions with feedback so you know what to expect.
