How you practise it
Every lesson is followed by six kinds of question rather than one, because a
single format is a thing you learn to game rather than a thing you learn.
1Multiple choiceFour options, one right, and the reason underneath either way.
2Spot the errorA sentence with something wrong in it. Find it before you are told.
3Fill the gapThe word that belongs, typed rather than picked from a list.
4Match the pairRules against examples, until the pairing is obvious.
5Order the wordsA scrambled sentence put back the way English actually builds it.
6True or falseQuick, and unforgiving of a rule you only half remember.
