[LON-CAPA-users] Bubble sheets
Mon, 12 Jan 2009 21:09:02 -0800
Thanks for all replies on this. I planning to try bubble sheet exams
this semester. I found a Optical Mark Reader on campus (a Grade Master
by Appersson), and it'll output to file. The instructions in the course
coordinator manual do not specify any particular format on the "scantron
file." What is the correct format of this file? Is it just a comma
separated file with each line consisting of the student-ID and the
student answers for each problem?
