Have you checked the 9 conditions on Quebec immigration website?Did you observe that they said if you fall into one of the categories not just that you must have your AOT under category A,B or C.So,you can apply if you fall into one of the categories.Sure category E has zero point under AOT but if the person fall under another condition according to Quebec immigration,he can qualify.Show me on quebec immigration website that they said that it is only people in category A,B or C can apply.All the people that i have read of who had their application returned for the reason stated above had different work experience compared to their education.Some even had AOT on priority list but different work experience.
