<p>Okay, first off I'm Canadian and we don't use this system, which I believe is standard in the US:</p>
<p>A = 90-100
B = 80-89
C = 70-79
D = 60-69
F = 0-59</p>
<p>In Canada, each province has its own grading system. In BC, ours goes:</p>
<p>A = 86-100
B = 73-85
C+ = 67-72
C = 60-66
C- = 50-59
F = 0-49</p>
<p>I'm also aware that some schools in the US have "+" and "-" for every letter grade (except F), and that the GPA scales differently for those. For instance, I know Columbia calculates these and A+ is worth 4.33 per credit, not 4. Can someone tell me how the marks break down for these things?</p>
<p>Not knowing how to take these into account, I've used the standard American 4 point system. (So for instance, a BC 'A' of 88 in Socials 9, I've designated as a 'B' worth 3.00 points. Since in BC all courses, core or elective, are worth the same credits, and we don't use a semester system, the multiplying and dividing by credit worth is superfluous and I've plugged in the numerical letter grade values directly.)</p>
<p>My cumulative GPA from grades 9 to 11: 3.79</p>
<p>Now, with the issue of 'weighted' GPA. I'm told that honours and AP courses are worth more, but aside from the odd AP's (which are only available in two or three subjects max in my school), we don't follow the same program. For instance, we have no "Honours" classes. However, we do have "Accelerated" classes, again for a small handful of subjects. Should these be weighted? Also, in grades 9 and 10, I didn't take an "honours" math course per se, but I did take regular stream math two years higher respectively (so 11 and 12 respectively). Would this be weighted? Again, I have done so, mainly because I want to see that baby go up, but I don't know if this is what admissions will do.</p>
<p>I've weighted the courses by putting a '5' instead of a '4' for an A. There are different ways to weight courses, I know, but I don't how to do the other ones. Full list of courses I've weighted: Math 11 regular in grade 9, Math 12 regular in grade 10, Accelerated English 10, AP Calculus 12, AP Biology 11, Physics 12 in grade 11, and Accelerated English 11.</p>
<p>Weighted GPA (cumulative): 4.03</p>
<p>A couple more caveats. I've not taken into account a challenged AP, because I don't know if it will count as a separate course, especially considering that I was taking the regular course concomitantly. (Specifically, I challenged AP Physics B in grade 11 while taking a non-AP Physics 12 course in grade 11. I didn't count this as another 'A' course, because I already weighted the Physics 12 'A' for having taken it in grade 11, and adding this on top would feel too cheap, even by my standards.) </p>
<p>Finally, I averaged out my grades 9, 10, and 11 marks, because I think that's the way they do it. Are certain grades weighted more? </p>
<p>My grade 12 marks aren't in yet, but they should be about the same.</p>
