Common questions

Before you take it to class.

Direct answers so teachers can decide whether Corrigi fits their routine.

Do I need a scanner or special paper?

No. The idea is to use regular paper, a regular printer and the phone camera to read QR Code and answers.

Does the QR Code replace the answer key?

No. The QR Code identifies the exam and the version. The answer key is still the sequence of answers Corrigi compares against the student's marks.

Can I review before locking the score?

Yes. The grading shows up for review. The goal is to speed up reading and keep the teacher in control of the result.

Does it work for large classes?

Yes. The flow was designed to grade many sheets in sequence and then show the consolidated class view.
