I've never used it.  It has some glitches, like you can't plug in the same book for two different grades. If there's a way to do that, I couldn't find it.  I frequently double up my kids on some subjects and for the life of me couldn't figure out how to get the program to recognize that.  It wants to assign a code to every book, etc., which just doesn't work for me.

I just use a spreadsheet for my kids' lessons now, but in the beginning I gave them a half sheet every day with their assignments on it.  They just checked off the assignments as they did them, and that worked out.  When they're done with an assignment, I log it on a form that has lines for assignments, a separate area for quizzes/projects, and another area for tests.  When figuring a grade, I total each of the three areas separately, then add the three scores together.  Then divide by three and you get the total grade. It's the simplest way I know!  I grade everything on a percentage, so that makes life easy for me.
