I bought mine 6 or 7 years ago, the basic version on cdrom at a homeschool convention.
I enter the background information and subjects for each student, and at the end of four years I use the program to check and print the transcript. Each year I add the grades for the year, and the program figures their GPA.
The program told me that I didn’t have any fine arts credits for my son, so I added them. He did fine arts, I forgot to type them in.
You can make a study of transcript creation, or like me-learn enough to get by and produce a credible-looking document with the help of software.
I like that Transcript Pro allows me to use the product for many children and that it is offline.
