02 — Capabilities

Everything OnQ doesn't show you

OnQ only shows individual marks,never your weighted grade or GPA. Eight tools fix that, quietly, inside the page you're already on.
  • F.01

    Live weighted grade

    Calculates your true weighted average the moment a Grades page loads. Every category and drop-lowest rule from your syllabus, applied automatically.

  • F.02

    Projected final mark

    See what you're on track to finish with before exams arrive. Know whether to push harder or reallocate your study time across courses.

  • F.03

    4.3 GPA mapping

    Your percentage maps to Queen's official letter grade and GPA point value automatically, using the scale published in the academic calendar.

  • F.04

    Goal seeker

    Enter a target grade and get the exact score you need on each remaining assessment. Works across every weighted category, respecting drop rules.

  • F.05

    What-if simulator

    Adjust any grade before you write it. What if I get 55% on the final? Watch the ripple through your weighted average and GPA instantly.

  • F.06

    AI syllabus scanner

    Click Sync Syllabus on any course and the AI reads your PDF automatically, extracting weights, drop policies, and conditional rules like "best four of five labs."

  • F.07

    Drop-lowest rule engine

    Handles "drop lowest quiz," "best N of M," and conditional weight shifts the way your professor actually wrote them. Not a naive average of everything.

Why Queen's students built this OnQ grade calculator

OnQ (D2L Brightspace) shows you individual assignment marks but never your weighted course grade or GPA. Every Queen's student ends up building a spreadsheet, manually entering category weights, and re-calculating after every submission. OnQ GPA automates all of that.

It was built specifically for Queen's University students on onq.queensu.ca. D2L Brightspace uses web components and shadow DOM, a technical architecture that most generic grade calculators cannot read. OnQ GPA uses deep DOM parsing to scrape your live D2L grades and apply your syllabus weights in real time, on the page you're already on.

Works for every Queen's faculty

Whether you're in Arts & Science, Smith Engineering, Commerce (Smith School of Business), Law, Medicine, Education, or any other Queen's faculty. If your course is on onq.queensu.ca and has a Grades tab, OnQ GPA can calculate your weighted grade. The AI syllabus scanner understands grading schemes across every faculty's course structure.

Your grade data stays on your device

All grade calculations happen locally in your browser. Your grades, GPA, and course data never leave your device. The only external network call is the optional AI syllabus scan. Before sending, the extension automatically strips all personal information (emails, student IDs, phone numbers) from your syllabus text.

  • No account required
  • No data collection or tracking
  • No ads, ever
  • All calculations run in your browser
  • Free for every Queen's student
  • Grades never leave your device

How do I calculate my GPA at Queen's University?

Does OnQ GPA work with D2L Brightspace?

Yes. OnQ GPA is built specifically for Queen's University's OnQ platform, which runs on D2L Brightspace. It reads your live grades directly from the D2L Grades tab using deep DOM parsing that works with D2L's web component architecture.

What GPA scale does Queen's University use?

Queen's University uses a 4.3 GPA scale. A+ = 4.3 (90–100%), A = 4.0 (85–89%), A− = 3.7 (80–84%), B+ = 3.3 (77–79%), B = 3.0 (73–76%), B− = 2.7 (70–72%), C+ = 2.3 (67–69%), C = 2.0 (63–66%), C− = 1.7 (60–62%), D+ = 1.3 (57–59%), D = 1.0 (53–56%), D− = 0.7 (50–52%), F = 0.0 (0–49%). OnQ GPA maps your percentage to this scale automatically.

Can it handle drop-lowest rules and bonus marks?

Yes. The grade engine handles 'drop lowest quiz', 'best N of M', conditional weight shifts when a category is dropped, hurdle marks, and bonus marks. These policies are parsed automatically from your syllabus PDF by the AI scanner.

Does OnQ GPA work for all Queen's University faculties and courses?

Yes — OnQ GPA works for any course on onq.queensu.ca regardless of faculty: Arts & Science, Engineering, Commerce, Law, Medicine, or any other Queen's faculty. As long as your course has a Grades tab on OnQ and a syllabus PDF with weights, OnQ GPA can calculate your grade.

How do I set up the AI syllabus scanner?

Open any course on OnQ, find the syllabus PDF in the Content tab, and click 'Sync Syllabus'. The AI reads all weights, drop policies, and conditional rules in about 15 seconds — no setup required.

What if my professor changes the grading weights mid-semester?

Re-scan your updated syllabus PDF anytime by clicking 'Sync Syllabus' again. OnQ GPA will overwrite the old weights with the new ones. You can also manually override any category weight directly inside the extension without re-scanning.
