An AI exam checker is the review you run after Graider has marked a stack of paper exams against your own answer key or mark scheme. Before those marks go home, you read the calls you would want to explain, change any score your judgment would set differently, and release the version you can stand behind.
You upload the exam and the answer key. You photograph the stack. Graider marks against your own rubric and key. You review and override, toggle feedback, and keep the pen. Then you hand the exam back as a PDF or an email.
Graider is the AI red pen for paper grading, a product of DM Liquidity LLC. The public site is graider.org. Applying the key and mark scheme to the photographs is the work of AI exam grading. Preparing that mark scheme is covered in AI exam grader. This page stays with the check you run once those marks are on the scripts. A stack of quizzes or unit tests has its own check in AI test checker.
Your mark scheme. Their scripts. You check every mark. You keep the pen.
Use one order on every script, then one pass across the stack. Handwriting comes first. Split points, alternate answers, the total, and your grade boundary follow. Comments are the last decision on the page.
Walk each script in this order:
Keep the mark scheme beside you. Each kept mark should still point at the row that produced it: the accepted answer, the points, and the condition for partial credit. When a row and a script disagree, the check is where you decide.
The Low confidence badge is the flag on a hard-to-read answer. A faint pencil line, a letter written over another letter, or a word pressed into the margin can carry it. On an exam, start with every badge.
Open the page. Read the line the student wrote. Compare it with the row on your answer key or mark scheme. When the line matches a response you accept, keep the mark at the points that row earns. When the line is still hard to read, set the score you would give after looking at the page yourself. Override any score you disagree with.
A page that is too dark, cropped, or blurred deserves another photograph before you rely on the mark. The badge marks the place where handwriting needs a teacher. The score students see is the score you kept.
Partial credit and method marks are the rows you will be asked to point at. The setup earns its points. The working earns the next part. The final value, with the unit the question asked for, earns the rest. A common wrong answer can earn some of the points, with the comment you already write for that mistake.
Open a script where the working is sound and the last line is wrong. Confirm the points match the split on your mark scheme. Open a script where an earlier number is wrong and the later lines follow that number correctly. Apply the follow-through rule you wrote on the key. Where two methods are mixed, or the writing runs into the margin in a way the key leaves open, set the mark yourself.
Some exam questions also ask for a labeled diagram, a graph, or another drawing. Open that drawing during the check and set the score yourself. Diagrams, graphs, and drawings are yours to mark. Written labels and values around the drawing stay in the check against your key.
An exam question can accept more than one full-credit answer. A second method you teach, an equivalent form of an expression, a synonym you already count, or two conclusions that both fit the source can belong on the same row. When the key lists them, the check confirms the script used one of those answers and received the points that row names.
Read for a correct answer the key still needs. A set of scripts often shares one extra wording: a second formula that reaches the same value, a date in another form you accept, or a phrase that matches the meaning you already reward. When you would give that wording full credit with a red pen, write it on your copy of the key and override the marks that missed it. When you would give it part of the points, write those points on the row and apply that decision to every script that used the wording. A near miss can sit on the same row with the points it earns: a spelling slip on a technical term, a missing unit, or a response aimed at the neighboring part. Write that call once and use it across the stack.
When the question marks are the ones you will defend, add them. Compare that sum with the total printed on the exam and with the total shown for the script. A changed method mark that never reached the total, or a part left out of the sum, is the slip this pass is for. The total you release is the sum of the marks you kept.
Grade boundaries come from the scale your course already uses. A pass mark, a letter band, or a cut score printed for this exam is a rule you apply to the confirmed total. When a total sits on the line between two bands, apply the rule your department already uses for a mark on the boundary. The grade that goes home is the one you would explain to a student who asks.
After each script has a total you trust, read across the set, one question at a time. Choose a question where partial credit can be applied two ways. Pull several scripts that made the same move: the same missing unit, the same alternate method, the same follow-through from an earlier wrong number. The points should match. The comment should match.
When you override one script, carry that decision to the other scripts that fit it. When a script differs in a way that matters, mark that page on its own terms. A second method, a crossed-out line, or a drawing you are scoring yourself belongs on that page alone.
Keeping the pen means your key stays the source of truth, and the score on the script is the one you release. Override a mark when your judgment and the first pass disagree. Change the points. Edit the comment so it matches the note you would write in the margin, in your own words.
Toggle feedback on or off for each script. Turn comments on when they should go home with the score. Leave them off when the class will talk through that question and the score is enough for the handback. The words a student reads are the words you kept.
After the check, hand each exam back as a PDF or an email. One PDF per student holds the score you kept on each question, the total, and the comments you turned on. Apply your grade boundary the way your course already records grades. Email that file, or return the PDF through the path your school already uses. You keep the pen until that file goes out.
An AI exam checker is the review you do after paper exams have been marked against your own answer key or mark scheme. Graider is the AI red pen for paper grading. You upload the exam and the key, photograph the stack, and Graider marks against that key. You then check Low confidence badges, partial credit, questions with more than one accepted answer, totals, and your grade boundaries. You override, toggle feedback, keep the pen, and hand the exam back as a PDF or an email.
Review answers with a Low confidence badge, partial credit and method marks, questions where the key allows more than one answer, the total on each script, and the grade boundaries your course already uses. Then read the same kind of answer across the stack so one call stays consistent. Override any mark you would explain differently, toggle feedback, and hand the exam back as a PDF or an email.
The Low confidence badge is the flag on a hard-to-read answer. Open the photograph, compare the line with your key or mark scheme, and override the score when the page and the first pass disagree. Diagrams, graphs, and drawings are yours to mark.
You do. Add the question marks you kept and compare that sum with the total on the script. Then apply the pass mark, letter band, or cut score your course already uses. The grade that goes home is the grade you would explain.
Yes. Override the points, edit the comment in your own words, and toggle feedback on or off for that script. You keep the pen. Students see the score and the comments you kept when you hand the exam back as a PDF or an email.
Photograph the scripts, check every mark against the answer key and mark scheme you trust, and hand the exam back when you can stand behind the scores. You keep the pen.
