Anyone think they had improved but actually did worse?

<p>So I am kind of freaking out about my Oct test. It was the last time I could take it so I can't change anything and I've already sent it to the schools.</p>

<p>I feel like I did better than the last time I took the test but I'm just not sure. Has anyone felt certain that they had done better but ended up actually doing worse?</p>

<p>I have felt that way vice-versa: I felt i did bad but it turned out i did good.</p>
