In some exams two part OMR sheets are used. One side contains the blocks in which candidates need to give their identification details, and the other part contains question blocks with bubbles or checkboxes for marking the answers. The part containing the answers is sent for evaluations, and the part containing candidate information is passed on for inputting in the institute’s database.
This type of OMR sheets are used in the government recruitment examinations. Its main aim of use in such examinations is to provide confidentiality so that no person can manipulate the sheet. The details of the candidate are detached from the OMR sheet so that it is not possible to identify the candidate while evaluating the answer sheets. This type of sheet is mainly used in IIT -JEE, AIEEE, AIMS and many more competitive exams.
Barcode is printed on the both parts of the sheet. When the details of the candidates detached from the answer sheet then after scanning of OMR answer sheet, the barcodes are matched so that the candidate can be accurately identified.These sheets are used in government recruitment examinations so that no manipulation can be done by external person.
This OMR sheet is used in many competitive examinations to prevent any fraud or cheating. The mechanism of this sheet is very simple. This sheet has two detachable parts. One part contain the candidate roll no and other important details. The other part contain answer sheet.
These two sheets are collect separately and their bar coded is scanned. After the scanning of both sheets, they are combined with the help of barcode. It provides confidentiality and also makes the process very fast.
