IDC Theory and Standards Preparation Course

Online Course

Are you confident to pass your PADI IDC and IE exams?

PADI IDC Theory Preparation

PADI Course Director Steve Prior takes you though every IDC topic. Videos and lots of quizzes and exams to help with your PADI IDC Theory Preparation. 
All theory subjects, with typical PADI questions and answers. 
Brush up on the latest PADI Standards with 5 mock exams, all based on the latest PADI Instructor Manual. 

Why should you prepare for your PADI IDC written exams?

PADI often update their Instructor Exam questions. 

Of course we all know that PADI Standards change and we see the PADI Instructor Manual update every year. It makes total sense to be on top of those changes.

But PADI theory questions change too!

As times change, PADI alter the emphasis on some subjects, while others completely disappear from the exam papers. 

It’s important that you keep up to speed with those changes.  

How do you prepare for your PADI IDC Theory?

PADI products and other Websites

Some people use PADI manuals, digital products or visit a PADI Instructor for help. 
Others look online for websites to help with Dive Theory. 

For many people these solutions help – but not everyone.

An alternative way to learn PADI IDC Dive Theory

Over the past 30 years, I found that many people just “don’t get it” when they learn theory. 
They find that wherever they look, they get taught in the same way. Everyone seems to teach using similar methods, and for them – it just doesn’t work. 

So, over the years, I’ve developed a different way to explain the subjects. A simpler way. A way that is easy for people who are confused by the traditional ways. 
So although this online course leaves nothing out, it explains subjects in a way that you might not have seen before.

PADI IDC Theory Preparation schedule

The video lessons are very friendly and understandable. 

After each video lesson there’s a quiz where you can make sure that you fully understand things before moving on. 

Nothing is missing. 
I’d be amazed if you can find a question on a PADI IDC or an IE that isn’t covered in this program. 
Both Theory and Standards are covered. 
I know that you’ll enjoy working through the program. 

Increase your knowledge

As you work through the quizzes, your confidence will rise. Not only confidence to pass exams, but also confidence to teach the lessons to others. 
You’ll find a lot of great teaching tips in amongst the videos.
