I suggest that if you are going to use these courses, that you print up completed certificates (you make them) that include the name of the class, the date taken, and any projects completed during the course. These will be very valuable for future career and higher education entrances requirements.
Here is two links to the course lists (and I will include them in the "free section of my website as well).
Remember, it is not the amount of money you spend that will educate your children. It is the amount of research you do and the resources you choose to use that matter the most. Truly if money is an issue, a pencil, pad, a library card and the use of a library computer will get the job done.
May God Bless you and your precious babes with tons of love and laughter within your home.
