Score. How to improve?

<p>W: 62</p>

<p>Okay so I get 5 wrong and the errors range from everything. Basically I know why the original sentence is wrong, so I find the first clue and cross out 3 choices. Then out of the two choices I usually get it wrong. </p>

<p>So how to improve?</p>

<p>just study up common errors, it should just come to you which sounds right and which sounds wrong</p>
