Many universities use the concept of equivalent experience or externally acquired competencies to evaluate whether parts of a course can be 'ticked off' when a student has several years of experience in a work environment. No doubt a pilot with sufficient experience and perhaps the odd side task or two will be able to make use of such a procedure and thereby acquire a degree in less time than needed for a fresh out of high school student. Whether this is possible is completely up to the university and course applied for and is highly dependant on the experience of the applicant. It will also be up to the pilot to provide the needed evidence, it is not a question of plonking a licence and logbook on the counter and getting a piece of paper in return.
