It has taken me a year to get through all of my ratings after my ppl (instrument through CFI a couple weeks from now)... My ppl took about 8 months to get but I only flew once or maybe twice a week and I was working 50+ hours a week and going to school. Just started working commercially a couple months ago but time has been coming slow so far. About 20 to 25 hours per month right now. It should pick up soon though.
