Explaining low test scores...

<p>i have a surprisingly good GPA...about 4.2 weighted however i have really low SAT and ACT scores.
SAT: 1600
ACT: 21
US History: 640
Math L2: 540
i really think its pointless for me to retake the first two b/c 1) i havent been improving and i already took them 3 times and 2) too late for improvement. im taking the Math2 test in Nov.
my question is...should i explain these low scores in my essays? (im applying to UCs)
but i dont really have any legit reasons besides the fact that i am a really really bad test taker.</p>

<p>The UCs are totally aware of rampant grade inflation in CA public schools, high GPAs with low test scores. Look at how low all UC test scores are in general. You will do fine below the top 3.</p>
