I will elaborate on the post of

The process which I have been though, is relatively simple.
First, your most difficult exam will be the INRAT, the instrument written exam.
The two best resources are on-line. Dauntless and Harvs air.
I found these to have all the essential questions and references.
Prior to doing that, you need to read the publication called the AIM, what is called the AIP in ICAO...
Most of the theory you will already know down pat. The regs particular with respect to Alternate Minima will be very different, as will some of the airspace questions. The exam will assume you live in Canada and are familiar with all the place names etc. These assumptions were unexpected and difficult for me when I first wrote the exam.
There are irrelevant parts of place names, geographical knowledge that can cost you questions.
You need to practice the MET questions to gain a sense of how they assume you already know these place names.
You need the standard expected Proof of Experience...
Then the written exam for the licence, CPL ATPL etc...
Not that difficult if you have an SA ATPL...Just do the practice exams and you should have no problem.. at least I did not and the exam was easy compared to INRAT...
The INRAT contains a lot of breadth, its really the 5 subjects of ATPL in other countries rolled into one... It can have pre-solo questions to ATPL questions in it.
It is riddled with Which of the following is false...
Lots of comprehension questions that require
a high level of English comprehension.
If you know the material, and practice enough questions,
you will become familiar with most of the questions involving
Comprehension.
Once you reach a high level on the practice exams, you should have no
problem in passing the actual exam but, you are guaranteed that there will be questions in the real exam that you have NOT seen previously.
The Flight Test and PPC should be a breeze if you do some simulator to brush up on local approaches.
Hope that helps you..
