Diagnose my unstable writting score

<p>Hello ive been taking the BB practice test for a while now and keep getting a inconsistent writting score ranging from 720-550!!! and I am not exagerating. i know the BB are the most accurate, so it cant be becuase of the test. It has to be somthing wrong with me ! lol has this happend to anyone before??</p>

<p>And also would anyone mind posting their writting rules/techniques they usualy use while going through the writting section, please =)</p>

<p>thanks</p>

<p>The difference between a decent essay and a great essay is about 100 or so points. Its huge. If you're a good writer, there shouldn't be too much fluctuations. I, on the other hand, do well on some given topics but fail at others. We're all on the same boat when it comes to the writing section of the SAT.</p>

<p>The best thing to do is to learn from your mistakes. After a while, there won't be anymore mistakes for you to learn.
I was able to pull my writing score up to consistent 75-77 MC after a week of just doing writing sections.</p>
