Akindi is a software alternative to Scantron bubble sheet tests. Akindi integrates with a Canvas course and loads the roster automatically. You can then create answer keys and print out bubble sheets (on regular plain paper) for students to fill-out in class. Collect the sheets and use the scan-to-email function on the printer to scan the answers and send them to yourself as a pdf. The pdf is then uploaded into Akindi where it will be graded against your key.
