AlwaysAviating,
As a non Aerospace course graduate are you actually allowed to just opt to do the 5 hours course in the Aerospace department, will you have to pay additional fees? Depending on the course the 5 hours in that course may be 5 hours demonstrating various aspects of flight dynamics, ie: air experience for engineers as opposed to actually been the first five hours of the EASA PPL course. Description you gave suggest it is the first 5 hours of a ppl but worth checking to make sure. So if you are having to pay an additional fee you may be just as well put the money towards lessons at a flying school.
