The prices are based on minimums....so if you need extra lessons it costs you more. I would say the average student goes over 2-4 flt hours per step...an extra lesson or two. I needed that as a student, and my students have done about the same. Its just very hard to do it in syllabus time, thats all. There are ways you can cut it down...I have had students do lessons again because they didn't prepare hard at all, and just were not ready. That only costs them money. Those that were better prepared definitely saved money. I would say thats the biggest reason for students spending extra. Other factors include flying ability (most people are good enough, a few really struggle), your instructor, your willingness to fly 5-6 times a week (those that fly nearly everyday do better then those who fly 3 times a week). So...a lot of it is the student....if you work hard, it will save you money. But expect to pay at least a little extra no matter how hard you prepare.
