Another thing to look at if you want to save money on college costs is using AP courses and CLEP exams as both a way to get in high school core requirements while earning college credits through the exams.
The CLEP exam is intensive, so you'll find that in studying for the exam that your high schooler self teachers most of the core material he or she would have learned in a classroom setting.
CLEP and AP: One of the biggest advantages of homeschooling through high school is the ability to work on dual credits.
Find out which, if any CLEP and AP credits the university accepts and work on those first.
These exams include UExcel Exams, IT Certification Exams, AP Exams, and CLEP Exams.
