FormRead is a completely free OMR (optical mark recognition) web software for scanning and grading user-filled, multiple choice forms.
Create your formats with any of your office or drawing tools, scan them and parameterize their coordinates in an easy way.
Once you have parameterized your form, you can print many of them, give it to your students/respondents, scan and recognize them with formread, and you can finally export the data in your preferred formats...
