If you write word answers, be very careful to avoid misprints: e.g. oxalate – OK, oxallate – wrong.
If two-word names are needed, use a pattern: name1(gap)name2, e.g. sodium oxalate.



If you fill boxes of groups in structural formula (e.g. saccharides), be sure to use the correct
order how the atoms are connected to carbon (e.g. –OH is right, –HO is wrong).
