The sheer speed and accuracy of scanning. You can grade a stack of 50 to 100 multiple-choice tests in a matter of minutes just by hovering your phone's camera over the paper. It doesn't require a bulky Scantron machine or special optical paper—you just print standard bubble sheets on regular copy paper. The instant item analysis and question breakdown are fantastic for immediately seeing which concepts the class struggled with. Review collected by and hosted on G2.com.

The web portal interface feels a bit dated. When reviewing scanned sheets, navigating from one student's individual scan to the next can be slightly clunky because you often have to back out to the main list rather than simply swiping through papers. Also, custom bubble sheet creation on the website works, but it takes some initial trial and error to format. Review collected by and hosted on G2.com.
