Ways to improve your TOEIC score

Get longer and shorter. The first time you try a test, try checking every answer after you do it before you try the next one. The second time, try a whole section and then check the answers to that section. Continue making the parts of the test you do without stopping longer and longer until you can do a whole test without stopping. If you get bored after a few timed complete tests or you find that you are not remembering the language you have learnt from it because it is too much, alternate doing whole tests and doing shorter sections. You can also alternate doing the whole test and doing lots of examples of just one section, preferably one you are finding difficult.
