What is this supposed to mean?

<p>I took the SAT for the first time in Dec. 2009
I got a 1670 -
reading: 580
math: 530
writing: 560</p>

<p>I retook it in Oct. 2010
I only went up 20 points to a 1690
Reading: 590
Math: 540
writing: 560</p>

<p>I had never prepped for it at all, but still no excuses.</p>

<p>I took the ACT for the first time in Sep. 2010
I got a 25 composite
Eng: 27
Math: 23
Reading: 28
Science: 20
Writing: 27
Essay: 09</p>

<p>I then retook it Dec. 2010 and got a 29
Eng: 28
Math: 26
Reading: 34
Science: 27
Writing: 27
Essay: 09
-again this is with no prep</p>

<p>I would like to know why I had such a jump on the ACT, but not for the SAT.</p>

<p>Someone told me that the ACT is easier for ‘non-whites’
I’m starting to think that this is true.</p>

<p>I’m hispanic, female, low-income family, my mother had to drop out to get her GED, while my dad never made it past the 9th grade</p>

<p>I’m wondering how much of an affect my background had on my scores, if at all.
also, how will college admissions officers view this?</p>
