Hi MarvinP,

Sorry I wasn't more specific before. I have taken into account the weightings for each assessment, and so the 'running average' is based on the weighted percentages over percentage of course completed (which is the sum of weightings where marks have been entered).

I'd really appreciate a maths teachers opinion on this, so if you have the time check out how I have constructed the formulas and let me know what you think.

Cheers
