The revision sheets are designed to be used after all modules are taught as they interleave and revisit vocabulary from other topics, as well as festivals. Please note that this mainly focuses on cultural festivals such as Christmas, birthdays and New Year etc and focuses on grammar. It doesn't go into detail regarding Day of the Dead or San FermΓn. The revision sheet does go into related vocabulary such as 'toros', 'corrida', 'quemar', 'rezar' etc. which aren't recycled as much in other topics.
In addition to the vocabulary related to festivals, the sheet also explicitly revisits the imperfect tense and talking about festivals in the present tense.
