Give one mark if all final burette readings (except any labelled Rough) are to 2 dp
and the readings are in the correct places in the table.
Do not give this mark if “impossible” burette readings (e.g. 23.47 cm3) are given (initial or final readings).

does that mean that we 'have' to give 23.45 instead of 23.47, or in this case give 23.50?
