That is incredibly impressive. Finishing Calculus by 16 is more the norm. How did you do the college general courses? AP? CLEP?
Homeschoolers are doing it all the time. That is why we must consider abandoning brick and mortar, and lock step progress through the years.
Regarding getting into college:
I had to go back to work briefly in order to work the number of hours needed to maintain my professional license. So...I took my 3 homeschoolers over to the community college to have them tested. I wanted to know what grade they would be.
My kids at ages ( 13, and 12) did soooo well that the community college adviser suggested enrolling them in the college. When the youngest turned 13 she did the same.
There is perfectly wonderful and inexpensive curriculum available thanks to homeschooling. This is why I believe conservatives, if they start private educational foundations, should abandon the idea of brick and mortar schools. Why not just fund the teacher? She could run her school in her home, a day care center, as part of a dance studio, or a store front office.
Why should the zoning and health regulations for this type of “mini-school” be any more onerous than for someone running a baby sitting service in their home, or dance studio, or Sylvan tutoring center?
