Is it possible to self study instead of taking a course for the NEBOSH IOG and pass the examination?

Hi, I highly recommend you to attend the class room based sessions to be able to clear the classes. 

No, It is always good to attened the class room training and get proper guidance before attempting for the Examination. In addition, you apply for an online course too.

NEBOSH IOG is and intense program self study is possibe there are options of Elearning  but classroom sessions are recomended 

It is much better to attend the classes for better result

Hello,
it is not easy to pass the exam without classes. its much preferable to attend classes for better results 

Yes, you can but It's better to take the whole course.

Attened the class better but for self preparation on websites
