Confused by a part of University of Toronto's engineering application?

So the academic requirements for U.S. students are listed as the following on UofT’s website:

"Grade 12 at an accredited high school with a high, grade point average and high scores on SAT Reasoning/Redesigned SAT (including Essay) or ACT exams (including Writing Test Component). Excellent results in senior level (AP, Honors or Equivalent) courses, including Math (Calculus), Chemistry and Physics.

Competitive applicants are encouraged to have two years of Chemistry and Physics as well as Calculus completed or in progress by their senior year. AP or SAT Subject Tests results in Calculus, Chemistry and Physics are highly recommended, but not required.

Applicants who have written AP exams should present minimum scores of at least 4; SAT Subject tests in Math, Physics or Chemistry should be at least 650; ACT with scores of 26 in Math and Science. Please note that U of T Engineering does not grant advanced standing credit for AP courses."

So in the engineering applicant profile under the “Academic Profile” section, there’s a part where they want me to provide all my course grades for the pre-requisites. This is where my problem is: I don’t understand some of the course categories.

Can someone please explain what is Math 1, Math 2, English 1, English 2, Pre Calculus 2, Chemistry 1, Chemistry 2, and Physics 1, Physics 2?
Do the numbers mean that it’s my second year taking that course or does it mean something equivalent to honors? I figured out how to categorize most of my AP classes (like Phys C and Calc BC).

I’ve listed the classes I’m having trouble categorizing below along with the year I took it and any other relevant notes:
Honors Pre-Calculus/Calculus A (10)
World Literature (10, English)
Honors Chemistry (10)
Honors Physics (11)
AP Statistics (12, does this count?)
Creative Writing (11, English)
Science Fiction (11, English)
AP English Language (12)

Thank you in advance.

Oh, and another more minor question is if UofT actually contacts every single reference email provided for my extracurriculars to double check? I feel like given the applicant volume an act like such would be absurdly time-consuming…

I doubt they contact every single reference. However, since you are outside Canada and if they are deciding between whether or not to offer you or other candidates admission, they might contact the reference.

I believe the numbers mean the year you took the course. eg. physics 1 = first physics course taken ie Honors Physics and physics 2 = second physics course taken eg AP Physics. Canadian students don’t normally take anything above calculus and engineering admissions will be more focused on your calculus grade than your statistics grade, so just make sure one of the math lines is your Calculus BC grade.

Make sure to submit any AP or SAT subject test scores, especially in math, chemistry and physics.
