The calculator is an application in Facebook and learn more about it here. As said before, the calculator can also compute the CGPA of the student.
Yes, it is so awesome like that.
To try it, just go to http://apps.facebook.com/dlsu_gpacalc/ and compute your grades!
Or, just like its application page here.
Well, the application interface is different than before. As a matter of fact, I think that it is now easier to use. I just re-tweaked the code yesterday.
Any comments about the app? Just type it below.
