A not so gentle reminder on Grades Items on an assignment have a Mark value per item.
The Percentage earned on the assignment is calculated by taking the
Marks earned/Marks possible * 100%
Points are determined by taking Percentage earned on the assignment * the points allocated to that assignment.
Test are 50% of your grades, the rest of what you do in and out of class is the other 50%.
Formative assignments are a cumulative value of 50% of the Course. If there is 280 points allocated to Formative and 2 of those are for a written assignment like a worksheet at 3 points each that means (6/280) * 50% = 1.07% of the course. Which does not seem like much until you miss a few easy assignments and suddenly you cannot pass the course, or are always get an A on the test, but are barely scraping by with a D for the course.
Now the Summative assignments can really affect your grades. If there was 56 points allocated to Summative assignments and 20 of those are for the final, means that (20/56) * 50% = 17.8% of the course.
So the last thing you ever want on an assignment is a zero as a zero is a grade killer.
