Some OMR Sheets require the candidate to keep a counterfoil with him. Some are like forms where the candidate keeps the acknowledgement with him. There is always a clear Cutting Line printed on the sheet. This line must be strictly obeyed. Generally the sheets to be torn apart are separated by a perforated line. This perforated line is very close or overlapping the printed tear line. If the perforated line is available, then the perforated line should be used to tear apart the sheets. But if there is no perforated line, then the printed Tear Line should be strictly obeyed.
