SAT OR ACT and standardized test math help

<p>Hi, I am a hs junior from SC who is wondering if there is a big difference between the SAT and ACT in terms of weight (like is SAT better). I have better ACT scores:</p>

<p>ACT Composite-28
English-34
Math-22 (really low)
Science-28
Reading-27
Writing-11/12</p>

<p>SAT-1780
M-580
CR-610
W-590 </p>

<p>So, should I take the ACT more or the SAT? Need to work on math either way, advice on that too? Thanks.</p>
