From experience having been through an apprenticeship in the rotorcraft industry, I would say Vortechs is right as I did not finish it with the company I started with, but it was worthwhile.
Now running my own rotorcraft engineering company, I would say that personally I feel that a lot of the college courses available at the moment are a waste of time due to a lack of true hands on experience, I get many C.Vs through begging for work experience from students at these places, the best engineers I have worked with have done it starting from the bottom as a fitter or through the forces.
