T'was a long time ago for me but in '83, 26 years of age, married with two children, a new born and an almost 2 year old, I went the full time CPL course route.
My reasoning at the time, was a firm belief that if I tried the part-time route, something would get in the way. The garden would need mowing, or money would be tight this week, or yadda, yadda, yadda.
In 9 months I went from zero to CPL with MECIR. At times post gaining my CPL I wondered about the school, NASA/CATA because I heard so much negative stuff about the place from people who'd never been there.
Close to 30 years later, I'm of the opinion that one's frame of mind, desire to learn and self discipline are far more important & relevant than whether its school A, B or C. If I had my time over again, I'd go the same route. For me, too many distractions trying to do it part time.
