Today, I discovered that the meaning of revise to do with studying is used in British, Australian and New Zealand English, rather than American English:
(UK, Australia, New Zealand) To look over again (something previously written or learned), especially in preparation for an examination.
I should be revising for my exam in a few days.
What would be the American English equivalent?
To look for equivalents, I tried looking for synonyms, and I couldn't find any synonyms of this meaning of "revise" in Merriam-Webster.com's thesaurus section, thesaurus.com, wordnet online or the Oxford American Writer's Thesaurus.
