AI grading for science exams in physics, chemistry, and biology

Diagrams graded as drawn

Science answers are often drawings: a free-body diagram, a circuit, a reaction mechanism, a labelled cell. For an answer with a drawing, the grader sees the picture of the answer's box alongside the text read from it, so arrows, labels, and shapes count.

Equations, numbers, and units

Equations are read as notation and shown typeset beside the scan. Your rubric decides what earns the points: an item for the correct equation, one for the substitution, one for the value, and one for the units.

An equivalent form earns the same credit, such as one half and 0.5, unless the question or a rubric item asks for a specific form, such as simplest form or a number of decimal places.

Multi-part questions

A question with parts, such as 2(a) to 2(d), is outlined as one question with its subquestions, each with its own points, box, and rubric. Shared material above the parts, such as a figure or a data table, stays with every part it belongs to.

Feedback students can use

Each suggested mark comes with a short reason in plain words. Before you approve, you can edit the comment the student will see, add your own, or reuse one you already wrote for the same mistake. Students then see their graded exam with the rubric items that were applied, and can ask for a regrade if they disagree.

Built for large lecture courses

• Scan the whole class as one PDF; students are separated and matched to the roster.
• Invite teaching assistants as graders, with each mark showing who gave it.
• Grade one question across the class, and see how students answered it.
• Publish approved grades, or export them as a CSV file.

Nothing is final without you

Every suggested mark waits for a person to approve it. See how GradeOptics grades handwritten exams for each step from scan to published grade.
