DESIGN OF BASED ELECTRONIC CHECKER FOR STANDARDIZED ENTRANCE EXAMINATION

This thesis presents the hardware and software design of the PC based electronic checker systems for standardized entrance examinations. The system consists of PC, printer, sensor circuits, multiplexer. The PC including designed software manipulates the operation of the system and the printer. The printer is used as feeder of the answer sheets answer key. The sensor circuit senses the shaded area in answer sheet and keys. The feeding of the answer sheets is the same as feeding paper in a printer. Items are answered by marking specified areas of the examination sheet with the use of carbon pencil. The answer key sheet is to be scanned first and to be stored in the memory where the rest of the sheets to be scanned are being compared with. The shaded area of the scanned sheets as well as the results of the scanned answer sheets such as name, ID numbers and scores are displayed in the monitor and can be manipulated through the software, programmed in Turbo C++. The software is capable of sorting the names and ID numbers, searching records, ranking the scores, and also provides the database used. The developed system will be beneficial for every faculty or admission personnel at least to ease burden and save time for checking test papers.
