Worse SAT score on second attempt. What will the UC's think?

<p>So I just my second SAT today and feel that I did worse than my first attempt, perhaps a 100 point difference. (My essay this time sucked). I didn't study for the second one due to time and basically considered it a practice SAT. I am questioning if I should cancel my scores. I know that UC schools require all SAT scores and pick the highest one, but what will they think if my second score is significantly lower than my first score? Thanks.</p>
