I used a form I found at this website:

I did make some changes in it, such as eliminating the year totals and just having each semester grade listed. It worked quite well, and I liked the format.
For my first son, I used a different format. He had done some of his courses over a 2-3 year span, so for him I used a format that listed courses by subject, not by year taken. That also worked fine with the colleges to which he applied.
I did make annotations to indicate where each class was taken, as my sons took some at the local high school and some at the community college.
