experimental writing issue

<p>Hi, im worried about my score because i had 2 writing sections both 25 questions each. one was section 4 and the other was 6. my friend said he also had section 4 writing and section 6 writing but it seems that our section 6 was the same, but our section 4 was different. Do you think the section 4 writing was experimental since it seemed different, or even though our section 6 was same, it could be the experimental?</p>

<p>thanks</p>
