Q. I am fluent in French. My self-assessment suggests that I will get 68 points counting this. If I get 68 points, then I go through without an interview. Therefore, how do the authorities know I can speak French at all ?

Answer: In the absence of any evidence of your skills in French, an interview would almost certainly be required, at which time you would be required to demonstrate your abilities. A paper screening score of 68 is, by no means, a guarantee of an interview waiver.
