<p>“Haas is not guaranteed for freshmen, I was just comparing it because it was something I would have worked hard to get into if I end up going to Cal.” </p>
<p>Grammar lesson [sorry: can’t resist & applies no matter which school you choose]</p>
<p>“would have worked hard to get into if I end[ed] up” implies you’ve already decided to go to Dartmouth [needs the “ed”]. “would … work[] hard to get into if I end up” is the “going to Cal” sentence you might have meant.</p>
