I'd make sure that your kid has deadlines at least for some things before he/she starts college classes. I work at a small college and many of the faculty roll their eyes when they hear about a home-schooled kid because there is a good chance that the student will be unable to follow instructions for assignments that are listed in the syllabus and/or turn things in on time. As your child approaches readiness for college, I would advise creating specific assignments with deadlines, including some that your child will learn from but would not have chosen independently.
