First register with an ICDL Authorized Test Centre or enrol in ICDL Custom Testing.

We recommend you use Diagnostic Tests, which are reasonably priced, to get a “before” measure of your skills.  Then go through the courseware that you have purchased.
 
The CiA Training material available in Canada has been localized for use here and is very good for both self-paced or instructor-led learning. It consists of a series of 7 booklets shipped as a set. It is organized into a string of “Driving Lessons” that are short and sweet. At the end of group of lessons there are exercises that use data files you will have downloaded from the ICDL Canada website. When an exercise takes you through its paces and it calls for a file for you to work on you have it already on your computer. There is a progress record that you can use to track your way through the Syllabus. Your Diagnostic Tests will also reference the Syllabus. So when you need to work on particular skill areas you now know which they are and where to be particularly focused and thorough with the training material.

This approach when completed will help you be ready and confident to book a Certification Test. Some people do their tests one at a time. In Custom Testing it is necessary to do them in a maximum of three sessions. Many do all 7 tests in two sessions and occasionally some even do them in one.  If you are in an instructor-led program it would be a good idea not to do the tests until after the respective Module has been covered in class.
 
When you start you will have an idea of which Module is the most familiar. Since the tests are designed to be done in any order, a good way to do them is from the most familiar working toward the least familiar module.  If you are using Diagnostic Tests you will likely start with the best scores and work through the tests from there.
 
The Certification Tests have a normal time limit of 45 minutes. Well prepared candidates typically do the tests in less than 20 minutes.  You can see that if you are prepared for more than one module it is feasible to do two or three Certification Tests at a sitting. Once you start a Certification Test you need to finish it without leaving the examination workstation. But you can take a short break between tests if you notify your Certified Tester or Invigilator.
