How significant is my grade improvement?

<p>I went from having 2.00 - 2.50 GPA's, Freshman through Junior year</p>

<p>to</p>

<p>a 3.25 UW/3.75 W GPA, Senior year. This was also the first time that I took AP classes (2).</p>

<p>Will colleges look at the unweighted or weighted GPA difference? I know going to a 3.25 unweighted isn't too impressive, but since this is my only year taking AP's, will they look at my weighted GPA more?</p>
