I was that way. I quit reading books when the public school no longer allowed students to checkout books more than two grade levels above theirs. Then they went from jumping straight into new math each year to spending the first 10 weeks reviewing basics like addition and subtraction. And then they dumbed down the "accelerated" programs so that certain groups could have better credentials on college applications. So I quit "applying myself" at school and opted to complete high school in 3 years instead of 4 with minimal extra effort. The I dropped out of college after a semester because the coursework wasn't stimulating.
Just sayin'
Veggie, I am with you there. I made Cs in school, Cs in college without even going to class. Seriously, I just didn't go, never bought books, just took the tests and made Cs. I was bored. Why apply yourself if you could pass without the effort.
For the record- I fully support the right to home school, 100%. I just don't think it is for everybody.
