One thing that should be kept into perspective as well, is your actual aptitude for learning and how well you can teach yourself. It's imperative to show up to class prepared for the lesson, doing your "chair flying" at home, having your written exams done, so it doesn't hold up your training, etc. Even in a part 141 course, which is force-fed to you and laid out nicely, it still takes some work, using Youtube University (as it's known) to prepare. Your instructor is there to fill in the blanks, not teach you everything chapter and verse. I got caught off-guard with that when I first started training, so I give that advice to others starting off.
