This is just a quick script I threw together for calculating your grade average, grouping and overall class.
I have only bothered to add computing modules to the list - and remember only grades from 5th semester onwards count.

Note: I wrote this in 2008 and don't plan on keeping it up-to-date since I have now graduated :-) I cannot be help responsible if you don't get the grade expected!

Note: How the weighting works in this is my interpretation of the formula, don't blame me if this is wrong! The formula is available here so please check it!
