Apps Android Java Calculations HELP!

[sunami91]

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?

Welcome to AF sunami91. I moved this to the Application Development forum to get some better eyes on it.

University calculators are a bit different but I figured it out by looking at the source of the JavaScript code. I also made it so you can copy and paste if you want.

Here is the link the the pastebin with the code. Click Here

Glad to help.
