The SKILLS section of a PADI IDC Diving and the Environment exam can be divided into easy and familiar subjects: Open Water course skills, PADI Programs and questions from other PADI IDC Exam topics.
How it works
Open Water Course
Favourite questions focus mostly on two skills:
Emergency Weight Drop, where it’s important that the weight is dropped away from the body to avoid snagging on equipment and CESA where it’s important to keep all equipment in place, particularly the regulator.
Questions regarding the benefit of Discover Local Diving, where it’s beneficial to be introduced to a new dive site by local guides, and ReActivate, where divers can refresh the skills that are relevant to their individual needs and experience levels.
Other IDC Exam topics
You are likely to find questions from the Physiology Exam. For example there might be questions about Stomach (or Diaphragm) breathing. Also questions from Equipment Exam. For example, the importance of doing a weight check on the surface if you switch from steel cylinder to aluminium or vice versa.
