Was trying to find WAM calculators on the internet but was struggling to find any. My app is super lightweight and doesn't require internet connection once you install it and will instantly calculate your wam. Put it the total amount of credit units you've done so far and your current WAM and you'll be able to easily check how much a future grade will affect your WAM.

Also has a 'grade calculator' which calculates what grade is required in remaining assessments to achieve specified mark(i.e, if student is currently on a score of 90% with 30% of assessments left, the required grade on the 30% assessments to achieve a distinguish for that subject will be outputted).

I hope some of you find this useful and usable
