How the points are split across parts changes from question to question, so set it to match the scoring guidelines you're using. Each point gets its own toggle.

How to set up your files

Everything stays in this browser: your rosters, the PDFs you load and the scores you enter are not uploaded anywhere. Export a CSV when you're done grading.

1. Pick the course and question

Choose your AP course (Physics, Chemistry, Biology or Environmental Science) and the question you're grading at the top. Each question comes with its point split already set (A, B, C …). If your question splits its points differently, click Edit parts and match it to your scoring guidelines.

2. Class rosters

Easiest: one CSV for all your classes, with a header row and these columns. You can export something like this from your gradebook or student information system.

Period,Last Name,First Name
P1,Curie,Marie
P1,Feynman,Richard
P3,Franklin,Rosalind
P3,Hopper,Grace

Click Edit roster (or choose + Add period… in the period list), then Choose file…. Every period in the file is created at once. Other accepted layouts:

• A single Name column (or Student) with names written Last, First, plus an optional Period column.
• No file at all: type a period name and paste one student per line, Last, First (e.g. Curie, Marie).

Column names aren't case-sensitive, and "Class" or "Section" also work for the period. Duplicate names in the same period are dropped.

3. Student PDFs

• One PDF per student. It can hold one question or the student's whole free-response booklet; you pick the question you're grading at the top.
• Name each file starting with the student's name: Last First - anything.pdf, for example Curie Marie - Q2.pdf or Feynman, Richard - FRQ.pdf. "First Last" also works. Everything after the first " - " is ignored.
• When you load the PDFs, each one is matched to the closest roster name, even with small misspellings, and marked auto so you can check it. Names it can't match stay blank. Click the name box to pick a student; the closest matches are listed first.
• Scan pages right side up if you can. If one comes out upside down, press R or use the rotate buttons on the page.
• Scanning tip: most copiers can scan a stack into one PDF per student if you put a separator sheet between booklets, or you can split a class scan afterward in Preview or Adobe Acrobat.

Pick one period at the top to see only that class's PDFs (plus any not matched to a student yet), or choose All periods to grade a mix of classes, grouped by period.

4. Scoring guidelines (optional)

Click the Scoring guide tab above the PDF and upload the College Board scoring guidelines (PDF or image) for the question. Press G to flip between the student's work and the guide. One guide is saved per question.

5. Importing scores (optional)

If the papers have already been scored somewhere else (by an AI grader like Claude, by students grading themselves, or by a TA or co-grader), click Import scores. The imported points fill in for each student as a starting point, so you only check, edit and confirm (press Enter). The CSV needs a header row:

Period,Student,Question,Points earned,Comment
P1,"Curie, Marie",Q2,A1 A3 B1 B4 C1 C2 C3 D1,"A: Fw shorter than Fg at t2. B: ..."
P3,"Franklin, Rosalind",Q2,A1 A2 A3 B1 C1 D1 D2,

• Student must match the roster name exactly, Last, First. Put quotes around names that contain a comma.
• Question can be Q1, Q2 …, a number, or for physics the type (MR, TBR, LAB, QQT). Add a Subject column (Physics, Chemistry, Biology, APES) if the file covers more than one course; otherwise the course selected at the top is used.
• Points earned lists the exact points, separated by spaces: the part letter plus the point number within that part (B2 is the second point of Part B). If you only have part totals, use columns named A, B, C … instead (e.g. A = 3, B = 2); those fill the first boxes of each part.
• Comment is optional. Write it as A: … B: … C: … and each part's note appears under that part.

6. Saving your grades

Download CSV saves every student's points, part scores and totals, sorted by period. Open in Google Sheets copies the same table and opens a blank Google Sheet; click cell A1 and paste.
