Well, this is the page for the subject of Business Translation inside the Graduate Program. To the right you'll find its program, class texts and homework files. A mock test is also included here if you feel like having a test corrected in order to get the 'knack' of it, but remember it should take you less than an hour (including the first reading to get the context, register and topics right, the translation itself and the final proofreading).
You might also want to take a look at the Business English glossaries at the bottom: a popping message will inform you about their languages and topics.
