<p>When they make up the TAG applications they probably just list all of the majors that the school normally offers. Also, when you applied for TAG, mechanical engineering might have still been open. However, when the school actually has to make up the admission applications, before they can actually offer a program they have to be sure that they have the resources to accommodate additional students and due to the problems that kmazza listed they probably determined, on fairly short notice, that at this time they can not accept transfer students into their mechanical engineering program.</p>
