I been creating this grades calculating app and m having problems with calculations.
The app looks very similar to this website :
University Grade Calculator, calculate module averages and degree classifications - unigradecalc
My app is basically the app version of that site but i just can't seem to work out the formula. I guess i suck at maths. I know this is an android forum and I am asking maths related question but is there anyone out there who can help me?
