Candidates will not be allowed more than one attempt in Morse reception and sending test, the test may be written in ink or pencil but must be legible. Overwriting will be treated as error. If any correction is required the candidate may strike off the wrong character and write the correct one above the character. More than 5 errors will disqualify a candidate.
