How it works

Instructor

Upload the problem and key

Upload or paste the problem statement and your solution key. Use one key for the whole assignment, or attach a key to each question with its pages marked.

Files stay with course staff unless you choose to let students download the handout or, after you publish, the solutions.

Instructor

Add grader notes

Each question and each rubric item has notes for graders: alternative methods you accept, how strict to be about units or notation, how to treat an error carried from an earlier part.

These notes are how you set leniency. They go to the AI with the question when you run it, and they sit beside the rubric while you grade.

AI, when you run it

AI writes the rubric

The AI reads your problem and key and proposes questions, points and rubric items that add or deduct points.

No key for a question? It works out the key results itself and labels them as AI-derived so you can check them.

Nothing is saved until you save it.

Instructor

Write the rubric

Give each question rubric items worth signed points, or start from the default set (correct, minor error, missing justification, major error, blank) and edit it.

Instructor

Review and save the rubric

Edit any item, then save. Each save is a new version, and totals are always computed in code from the items applied, never by the AI.

Changing a saved rubric reopens the approvals it affects; earlier selections carry over as unapproved drafts.

Instructor

Turn on exact checks

For answers that can be checked exactly, such as controllability rank, characteristic polynomials, state-feedback gains and 2-D equilibrium, Partial Credit recomputes the student’s answer in code.

Each check reports holds, fails or inconclusive beside the suggestion. It never changes a score.

Instructor

Set dates and open it

Choose release, due and late-due times, whether late work is accepted, and per-student extensions.

Student

Students submit

Students upload a PDF or photos from the website or your LMS and confirm which pages answer each question. You can also upload a stack of scanned submissions yourself.

AI, when you run it

Run AI suggestions

You choose when it runs and on what: one question across every submission, or the whole assignment. It runs in the background, within a daily limit.

Thorough mode lets the model think longer before suggesting. It is on by default when questions are graded one at a time; it is slower and each call can cost several times more.

Every suggested item cites the page and expression it rests on. A mismatched problem version, unreadable work or unverified full credit is flagged instead of passed through.

Instructor

Grade by hand

Grade with the rubric alone, or copy a prepared prompt into the AI assistant you already use and paste its answer back to be checked.

Instructor

Review on its own pages

The question opens on only the pages that answer it, with its rubric beside them. Suggested items are marked; nothing is applied until you accept it.

Exact-check results, when turned on, appear beside the suggestion. Add a comment for the student if you like.

Instructor

Approve the submission

Approval needs a grade on every question and is tied to this rubric version and this attempt. A rubric change or a new attempt clears it, and you approve again.

Instructors and TAs can approve.

Instructor

Publish grades

Only instructors publish, and students see nothing before you do. Then each student sees their score for each question, the rubric items applied and your comments.

You can unpublish an assignment.

Automatic

Totals go to your gradebook

Approved, published totals go to the gradebook column you chose, when you publish and again when you ask. Unapproved work sends nothing, never a zero.

A score someone changed in the LMS is left alone unless you choose to overwrite it.

LMS integration

Instructor

Download grades as CSV

Download approved grades as CSV, as totals or per question, for any gradebook.

Instructor

Answer regrade requests

Students ask about a specific question while requests are open. You answer from one queue that shows the whole history.

Done

Approvals, reopened reviews, rubric changes and grade releases are recorded with their time.

Student

Open the link in your LMS

In Canvas, Moodle or Brightspace, open the Partial Credit link in your course. In Google Classroom, open the assignment’s link and sign in with your school Google account.

Student

Sign in

Sign in with a one-time email link or Google using your school email, or join with a code your instructor shared.

Student

Open the assignment

See the due and late-due times, including any extension you were given, and download the handout if your instructor shares it.

Student

Upload one PDF

Upload a single PDF of your work, scanned or typed.

Student

Take up to 40 photos

Photos are downscaled, contrast-adjusted and combined into one PDF on your device before upload.

Student

Match pages to questions

Mark which pages answer each question. They are filled in for you when the handout’s layout allows; check them before you submit, because graders open each question on the pages you chose.

Automatic

Submission saved

Every attempt is kept and gets an emailed receipt. Work after the due time is marked late when your instructor allows it.

Student

Resubmit

Upload again any time before the deadline. Earlier attempts are kept; the latest one is graded.

Instructor

Your instructor grades

A person approves every grade; the AI never grades on its own. You see nothing until your instructor publishes.

Student

See grades and feedback

See your score for each question, the rubric items applied and any comments. Your instructor may also let you download the solutions.

You only ever see your own work.

Student

Send a regrade request

Ask about a specific question while requests are open. Your instructor answers in Partial Credit.
