<p>Each major has a certain number of places. If there is a clinical lab major at UT (I’m not incredibly familiar with NatSci beyond knowing they have Bio and Math departments), then they will have a specific number of students to admit and will take the best qualified. Then you would be considered for your second choice, and then as an undeclared student. If smaller numbers apply then have space, I think you have a better chance, but I’m not sure.</p>
<p>The service hours go in to the personal index. Your ECs and leadership are 4/7 of the Personal Achievement Index and you will do well there. Essays are the other 3/7.</p>
<p>Standardized tests help a lot, I’m not going to lie. Just based on UT’s formula, the higher you score, your chances of getting in increase exponentially. Affirmative action can’t officially come in to play, so he likely got in just on his scores and leadership alone.</p>
