I gotta step in here, I know when I was an instructor, myself as well as the owner of my flight school, made it crystal clear that there is no set time for a license and we "guarantee" you nothing. Some people may take longer to learn certain things and I think you would be doing them a great disservice just to get them done. How an instructor can sign someone off for a solo, or check-ride who is not ready is beyond me. Some people seem to forget that if and when your students engine quits, when his family is in the back, its your training that hes is going to rely on, cause as cheesy as it sounds, their life may depend on it! You have to wonder about a school that "guarantees" you anything other than a safe a/c and a knowledgeable instructor. How can you say someone will be ready in a fixed amount of time, its flying an airplane..............
