Ways to improve your TOEIC score

Understand your biorhythms. By knowing whether you are a morning person or an evening person, you can plan which easy, mechanical things like learning vocabulary lists or doing pronunciation practice you can leave to times you are sleepy like after lunch, and which more challenging things you should do while you are most awake (for most people this is first thing in the morning, even for most people who think they are evening people). The same things are true over a week with Monday mornings, times just before the weekend etc.
