AHH So much to choose from!

After conducting my google searching to find different gradebook software I realized the unbelieveable amount of options out there. I decided to go with the basic gradekeeper for windows.
This is how the website explains it's pros and cons of the software:
which can be found at http://www.gradekeeper.com/

Version 6.5 makes the following improvements:

• Can now export email addresses
• Can now edit and lock the term grade
• Can include tardies in attendance deduction
• Missing extra credit work is considered excused
• Assignment scores report includes basic statistics
• Class summary report includes breakdown by grade
• Can click column header to sort by ID, name, or grade
• Can enter negative scores to deduct from points possible
• Can enter multiple email addresses in each student email field
• Can use up and down arrow to change assignment date by one day

I think I need to play with the software before I feel confident with it. But I think with time it will be a very helpful tool.
