2nd time shorter: Question 4 ALL experienced excavator professionals

Hello Everyone



I have an excavator question:



How long would you say it takes to learn: all the ins & outs; tricks; secrets of handling & maneuvering for digging & demo-ing homes?



I'm going to be taking a course which is 3 months long. Will I learn everything in 3 months of pure school theory and practical training to demo a house on my own without supervision? or is it a career that it takes 20 years to become a professional finally?



Thanks
