In my opinion, there are two aspects to this matter. First, all those who, like you, want to take exams in French must be allowed to do so. These exams must be available and be of equal quality. Second, to practise in Quebec, you obviously have to have a minimum knowledge of French. That's the case of all professions, whether it be engineers, doctors or lawyers, in particular.
