The simple answer is no. If you want to become a Canadian citizen, you must take the Canadian citizenship practice test. Even though the practice questions are not the official questions in the real test, they have several benefits.
First off, taking the practice tests means you have to read Discover Canada. This study guide is available online as a PDF or HTML document. You can also listen to it, download the guide or order a copy sent to your mailbox.
By reading the guide, you familiarize yourself with the rights and responsibilities of Canadians. Not only that. You learn Canadian history, geography, government, economy, symbols, and laws.
Second, the practice questions are usually based on Discover Canada, which is also true about the real test. As such, taking the practice test prepares you for the actual test. Basically, practice tests can help you achieve your desired results.
Third, the practice test helps to reduce test anxiety. A majority of people who prepare for tests such as the Canadian citizenship test often experience anxiety. The reason is simple; they fear to fail the test.
So, if you experience anxiety before a test, take the practice tests. They will improve your confidence before and during the real test.
Lastly, it reinforces learning. In fact, studies show that taking practice tests is more beneficial than spending your time on re-study. This is because practice tests simulate both studying and revision. As such, they encourage earlier learning and allow for space out learning.
