ok, i've been wondering about this a few days and thought you folks might be able to help
i've sat 5 tests so far (well, 4 really, cos we missed one) and my marks for those 5 are:
24/25, 17/20, 14/20, 0/40 and 18/30
now, is my average percentage the sum of the marks i have divided by the total available marks (e.g. (24+17+14+0+18)/(25+20+20+40+30))
or is it the average of the individual percentage scores?
any help would be appreciated, thanks
