Amel - the average is calculated on grades without decimals, so there's nothing to produce the .04. On the other hand, Veronica gave me the solution (the obvious solution...). The decimal is in the right place - only it is not written as a percentage. -- I thank you all for contributing! The job is delivered and accepted by the client.

As Joshua indicated in his answer, it is probably 60.04% (hence the four decimal places).

Thanks, Veronica! You solved the puzzle that shouldn't have been a puzzle. Still, the 4 hundredths, but let's leave them alone.

60% = 0.6

Nesrin, thanks for asking - The percentage is near the bottom of the table, where the totals and explanations are given. There are percentages in the explanation (e.g. Excellent >=85%), but grades are given only in words.
-- If it's a misplaced decimal comma (or rather a decimal point, my source document is very pale), it fits well into the percentage bracket for the student's average in words: Pass = 60% according to this certificate. Still, the leading zero puzzles me. As do the 4 hundredths, since all and every grade is "Pass".

Could you give us a better idea on where this percentage is found in the certificate? And are there other subject grades given as percentages, so that this would be their average?
