<p>As others have mentioned, there seems to be inconsistency between the IB predicted scores and GPA. </p>
<ol>
<li>It is prudent to rely on reputed credential evaluation services that would certify conversion of overseas high school scores to American equivalent GPAs, and send the converted scores directly to desired universities. Many US universities do accept scores from World Education Services. If OP’s parents are financially willing to commit ~ $70K/yr, it is better to spend $400/ on getting high school transcript evaluated & sent. </li>

<ol>
<li><p>There are many fairly good universities in the US that, for some reason or other, are not able to fill their capacity well beyond admission deadlines. One such university that has appeared in the last 2 years is Michigan Tech (MTU). It is known for engineering, but because of its relatively snowy location in Michigan Upper Peninsula, could be an admission safety.</p></li>
<li><p>It may be easier to gain admission at a regional campus, and transfer to main campus after 2 years. For example, University of Michigan, Flint, has a guaranteed engineering transfer program with Ann Arbor campus, provided the student meets various criteria (especially GPA). I am sure there are several more in such category (eg. Georgia Tech etc.). </p></li>
<li><p>Kettering university is a possibility, and so is Michigan State (MSU is certainly looking for competent full pay international students. </p></li>
</ol>
<p>Should evaluation by WES show a higher GPA than reported conversion by OP’s high school counselor, it would open up many more matches. </p>
<ol>
<li>If time permits, and inclined to do so, call the international admissions counselors at say 3-4 of the universities that denied admissions, and ask them (i) if a separate evaluation of your high school transcript by WES would be helpful in reassessing your credentials. (ii) If they would consider ACT scores from March 7, 2014 exam.<br>
Answers to these would provide you an idea if it is even worthwhile pursuing further any of the universities that denied you admission. University of Michigan, Ann Arbor, would be a big reach. </li>
</ol>
<p>Sometimes, it is more timely to speak directly with the counselors than relying on e-mail.</p>
