so at the end of the semester how do they calculate what grade you get? do they crunch everything down to a % and then if you get over 80% then u get a HD?
They add it all up, in proportion to what each assessment task is worth...
So you got 44/45 on an assessment worth 15% of your final grade - that's 14.67 marks towards your final result.
Say you also have an assignment worth 5% of your final grade and you get 7/10 for it - that's 3.5 marks towards your final.
Then say the final exam is worth 80% (15 + 5 + 80 = 100) and you get 96/100 for it - that's 76.8 marks towards your final.
You'd add up those final figures: 14.67 + 3.5 + 76.8 = 95 (results are rounded to the nearest whole number) = HD
(I know that's not the assessment structure for AFC1000, but you get the idea...)
