Ways to improve your TOEIC 5

See if you understand why it is wrong now. If you are studying on your own, a few weeks or months are trying an exam task look at your answers again and see if you have learnt something that now makes the answers you got wrong more obvious. If you still don't understand after looking at something three or more times, it is probably worth getting a teacher for at least 2 or 3 classes so you can ask them questions and stop making the same mistakes, or at least joining a study group so you can get the ideas of other students.
