<p>My oldest son went to community college at age 14 to take calculus as our HS only offered AP AB calculus. He was the youngest in the class by three or four years, but he really enjoyed the experience. The professor once e-mailed me to say that he was more mature than many of the typical college freshmen who were in her class. The college kids seemed more accepting of him than the high school upperclassmen did when he was a 13-year-old freshman taking pre-calculus.</p>
