Can computers spot when a candidate has made a mistake transferring the answers?
If more than one lozenge has been completed for one question, the computer rejects the answer sheet, which is then dealt with on an individual basis. Checks are in place to identify incomplete answer sheets, which are also then checked. Cases where all the answers have been entered incorrectly, e.g. by putting answer 1 to question 2, answer 2 to question 3 etc., cannot be identified. Candidates should be careful when filling in their answer sheets.
