PADI Dive Theory Revision for PADI IDC & IE

Water PressureStudy the IDC and IE revision notes on these pages to help you prepare for the Divemaster and Instructor (IDC) exams and ultimately the PADI Instructor Examinations (IEs) These guides are also valuable for Master Scuba Diver Trainers (MSDT) for their Staff Instructor Course.

The sample tests contained in these documents are not the PADI exam question and answers you will get on your IDC and your IE but they are of a similar type.

If you can answer all the questions and explain why the wrong answers are not relevant then you are ready for your IDC course.

Dive Theory Revision – Extra ideas to help you pass

I recommend you review some of the material you have to buy for your DM and IDC courses as this will be invaluable for you as a tool to achieve mastery in the theory subjects above, I suggest completing the Diving Knowledge Workbook and if you are interested or want to know more about a subject then cross reference it in the Encyclopedia of Recreational Diving. You can also re-do the open water / rescue / divemaster quizzes and exams (you will need to get he exam pack as part of your IDC required materials pack) as a final check before you begin your course Complete the PADI Instructor Pre-assessment Exam in the PADI Guide to Teaching which has replaced the Instructor Candidate Workbook.  Complete this exam on your own without reference so you can identify any weak areas that may need extra revision before the start of your course.


If you are an enriched air diver (Nitrox) there is also an enriched air section that allows you to brush up on the theory if you did your course some time ago, its worth noting that most IDC schedules now let you include Enriched Air (or Enriched Air Instructor) courses within them, this is an invaluable extra as Enriched Air along with Digital Underwater Photography seem to be the most in demand specialties at the moment.
