Quizzes should be easy to grade.
They are short. The answers are clear. The format is simple. But when you give a quiz every week to 80 students, that is 80 papers every week, and the grading never stops. You sit down on Friday evening, open the first quiz, check the answers, write the score, turn the page, and do it again. And again. By quiz 40 you are going through the motions. By quiz 80 you are writing numbers without really reading the answers.
The feedback students need from quizzes is different from what they need from essays. They do not need a paragraph about argument structure. They need to know which concepts they got wrong and why. Question 3 was about osmosis and half the class chose the wrong answer. That is not a grading problem, that is a teaching problem, but you will never know if you are just writing scores on 80 papers every Friday.
A quiz grader that gives instant feedback changes the game. GradeLab grades the quiz, tells each student what they got wrong and why, and shows you which questions the whole class struggled with. You spend five minutes reviewing instead of five hours grading.
You can add custom instructions so the AI grades the way you would. Tell it to give half credit for a partially correct short answer. Tell it to accept two valid approaches for the same calculation. Tell it to flag any answer where the student showed working but got the final number wrong. The AI follows your rules on every quiz, whether it is quiz 1 at the start of the term or quiz 35 at the end.
What Is a Quiz Grader?
A quiz grader is AI software that reads quiz submissions, scores them against your answer key, and gives each student specific feedback on what they got wrong and why. It also shows you which questions the whole class struggled with, so you know what to teach next week.
GradeLab handles multiple choice, short answer, fill-in-the-blank, and essay questions. It reads handwritten quizzes using OCR. It awards partial credit based on your rules. And it gives you class-level analytics that turn 80 papers of raw data into one clear picture of where your students are struggling.
You review every grade, override anything you disagree with, and approve before results reach students. The repetitive part, the part where you check 80 multiple-choice answers by hand, gets handled. The teaching part, the part where you decide what to review in next week's class, gets the data it deserves.

Quiz Grader FAQ
What is a quiz grader?
A quiz grader scores quizzes automatically and gives students instant feedback on what they got wrong and why. GradeLab grades MCQ, short answers, and even essay questions on quizzes. It shows you which questions the whole class struggled with so you can adjust your teaching. You spend five minutes reviewing instead of five hours grading.
Can I add custom instructions for quiz grading?
Yes. You write your rules in plain English and GradeLab follows them. For example: "accept both A and C for question 3 because both are valid" or "award partial credit for showing working." The AI applies your instructions on every quiz.
Does the quiz grader give feedback to students?
Yes. Every student gets specific feedback on which questions they got wrong and what the correct answer was. You can edit the feedback before it goes out so it sounds like it came from you, because it did.
Can I see which questions the class struggled with?
Yes. GradeLab shows you question-level analytics: which questions were missed most often, which topics need reteaching, and which students need extra help. This helps you adjust your teaching based on real data.
Does the quiz grader work for online quizzes?
Yes. Students can take quizzes online and GradeLab grades them instantly on submission. You can also upload scanned paper quizzes if your students take quizzes on paper.

Lecturer, Pure Mathematics, Germany
My students write formal mathematical proofs. On a convergence proof question, GradeLab correctly identified whether the quantifier structure was right, whether the chosen bound worked, and where the logical chain broke. It did not just check the final line. That is the part that matters.
Dr. Isabelle Fontaine
Associate Professor, Theoretical Physics, France
GradeLab evaluated a wavefunction normalisation problem across 140 papers and correctly flagged eleven cases where students had a correct final integral but had used the wrong boundary condition. That is precise, subject-aware marking.
Prof. James Fletcher
Mechanical Engineering, Thermodynamics, USA
GradeLab evaluated a question on entropy generation in a throttling process and correctly identified which students had omitted the system definition, which had applied the steady-flow energy equation incorrectly, and which had confused entropy change with entropy generation. That distinction matters in this subject and it caught it reliably.

Before GradeLab, I spent every Sunday grading papers instead of being with my family. Now I upload the batch on Friday evening and by Saturday morning, every student has already seen their feedback. That part still surprises me.
Maria Santos
Teacher, Escola Internacional de Lisboa
I teach four classes with 35 students each. I genuinely could not keep up with grading. GradeLab didn't just save me time - it gave me back the ability to actually know where each student was struggling.
Sarah Mitchell
Head of Academics, Wellington Grammar School
We trialled several edtech platforms before GradeLab. What stood out was that it wasn't just grading software - the student feedback loop was instant, and the quality reports for governors were exactly what we needed.
