high school gpa vs sat & act scores. HELP!

<p>so my GPA isnt that great.
I've always gotten high B's some A's
and C's in college courses that I've taken.
I'm a junior now and I wa wondering if I do well on my SAT and ACT will my GPA be as much of an impact oon my acceptance?
And would taking SAT Subject tests help me or are they just required for some universities?</p>

<p>Amazing Subject test scores can make up for not-so great grades. The SAT matters a lot and can make up for an above average GPA, but not a mediocre one.</p>

<p>is like a 3.5-7 above average?</p>

<p>Depends on the schools you are applying to</p>
