my mark is currently at a 55%, my test are woth 70% of my overall mark and the rest 30% is my examan. If i have a 90% on my test what will be my mark? what if i have a 85 or a 100%?
If your mark is currently at 55% and your tests are worth 70% of your overall mark, your current test grade only accounts for 38.5% of your overall mark (55% * 70%).
If you have a 90% on your test, your overall mark will be:
Overall mark = (Current mark * (100% - 70%)) + (Test grade * 70%)
= (55% * 30%) + (90% * 70%)
= 16.5% + 63%
= 79.5%
If you have an 85% on your test, your overall mark will be:
Overall mark = (55% * 30%) + (85% * 70%)
= 16.5% + 59.5%
= 76%
If you have a 100% on your test, your overall mark will be:
Overall mark = (55% * 30%) + (100% * 70%)
= 16.5% + 70%
= 86.5%
So, depending on your test grade, your overall mark will be 79.5%, 76%, or 86.5%.
