The mini-tests provide practice of each part of the test under timed conditions similar to those on the TOEIC test. They also help to reinforce the language and test-taking skills covered In the unit. Roughly half of the questions will focus on the tactics covered in the unit, while the rest are a random selection of question types appropriate to the test part. The tapescripts and explanatory answers in the Tapescripts and Answer Key booklet allow learners to analyze correct and incorrect answer choices.
