I have ran my own tutoring business since graduation back in ‘07. What I have found is that 40 hours of tutoring is equivalent to about a year, sometimes two of normal instruction. I have helped high school students make the jump to college because the college used to send me their most difficult students. Mostly because they didn’t want them! There really is no need for most of what the students do in school - most of it is busy work.

I remember when graphics programs came out, and designers were making the switch from drafting boards to computers. I bought a Mac, some graphics packages, and was functional in all of the programs within a week.
I was shocked when I found out that colleges were devoting semesters to each graphics package.
I call it "course bloat." It's a lot like research. You pay for research, you get research. You pay for courses, you get courses. You pay for results, you get results.
