Optical Mark recognition with MySQL database and PHP scripts
...The PHP scripts were very much dependent on scanned page size and resolution.
I have written the OMR page format and PHP scripts which are more flexible in nature. This script used horizontal and vertical guides to identify area to be analysed for MCQ answer checking and also identify and correct tilt.

The answer page and scripts can be modified easily with little change in major functions of the library.
