Sorry if I'm too late to answer this, but I'd like to clarify a few things in regards to Mac's 12 point system...it's a very,
very flawed system...and you've all stumbled upon why.
First to make a correction:
I saw someone post that 9/12 is 75%. The problem with this assertion is that the 12 point scale does not range from 0-100...it ranges from 50 to 100. A grade of '0' is anything below 50. So getting a 1 is actually 50-52 (I think).
So it can be approximated linearly, if you start from 50. So technically, 9/12 is "75% of the way from 50 to 100." But this also is not quite true! Why? Because the GPA is only linear from 50 to 80...it then turns into exponential growth (approximately) for the remaining grades, 10,11 and 12 (To see this, note that a 12 is anything between 90 and 100%...this is '10 possible percentages' while a 1 is '50-52'...only 3).
This sudden shift in rate of growth is where the problem arises. Since the math involved in computing 'regressions' and all that sort of thing are complicated, they associated mark ranges to each of the numerical grades. These can be found
here.
------------------------
So the ultimate question: Is 9.5 an 80? Or some kind of hybrid mark?
The answer is, because of this flaw, it is both...an 80 and a 78%.
1) A 9.5 is a GPA of 3.50, which corresponds to a grade of approximately 78%. This is used in terms of
raw data...using only one course.
2) A 9.5 is actually an 80 as well. To see how, suppose I take two courses. In the first, I receive a final mark of 82%, and in the other I get a 78%. These naturally, average to 80% right? But in terms of McMaster's grades, I get a 10, and a 9...which average to 9.5.
In other words, McMaster's point system 'screws you over,' it underestimates your average. When you have an 80% average, instead of having a 10 average, you may have a 9.5.
--------------------
So in short when looking at a SINGLE course, a 10 is an 80%...any less is less.
But when doing things such as computing your average (things that involve multiple courses), all sorts of funny things start happening, if the grades cluster in the 9-12 range...so the registrar accepts a 9.5 as being a mark of 80% (as I demonstrated above with the 82 and 78% grades). So yes, for scholarships, the cut off is 9.5: 80%.
Hope that helps.
