### HOW DO YOU ADD UP TH FINAL MARKS?

It depends on your jurisdiction. In Ontario, the term mark has a weighting of 70, while the summative and final exams have a combined weighting of 30.

To illustrate, let's do an example.

Term mark worth 70% of final grade - 70
Summative mark worth 10% of final grade - 80
Formal exam mark worth 20% of final grade - 90

Your overall final mark would be as follows

70 x 0.70 = 49
80 x 0.10 = 8
90 x 0.20 = 18
------
Overall Mark 75

Good luck,
