I'm an ESL teacher in Mexico.I've been asked to prepare a group of software engineers for a test in English.

They have poor English skills. I have access to prior tests, and can buy any books or cd's etc that I want. I have been thinking of a sight learning approach i.e. breaking the test down to essential phrases, and individual words and introducing, perhaps 5 phrases per day and drilling, drilling, drilling. I'm not sure that this is the best approach. The test is of software design, not English proficiency Can anyone offer suggestions?
