My daughter took an English Comp. class last semester as a 13 year old. She was testing the waters for doing more college courses. She did fine with the class in terms of grades etc. She felt awkward during some discussions because she did not have the life experience that some of the students had. There was a discussion regarding poverty and some of the people in the class were single moms and had used food stamps etc. She felt her opinions could not stand up to the "life experience" she was hearing about. I think she was a bit turned off by that. Maybe classes that do not have that kind of discussion would have been better. My daughter can pass as a college student as she is tall etc. Before you make a decision maybe you could do a trial run in a class at the school you might use and see how he likes it?
