About

Scan is an online bubblesheet grader that marks photos of bubblesheets.

It uses custom filters and a convolutional neural network to determine the location of question boxes and grid-ins.

When using Scan alongside Cloud, it will automatically update all your answers to your user.

Photos of the test must:

1. be taken directly above the test
2. have less than a 35 degree rotation
3. be in a portrait orientation

Additionally, you must use the Ivy Global SAT Test or the College Board SAT Test for Scan to recognize the question boxes.
