<p>Im undecided/undeclared right now. Engineering is a popular major, is it difficult to change my major to engineering? (I'm going to be a freshman this fall)</p>
<p>Yes, tell them early.</p>
<p>It's impacted so they might have to review your scores/transcript.</p>
<p>My son was in the same position last year, and 2 colleges said he could not change to engineering at that point because they accepted all they needed. One said he would have to apply all over again at the end of freshman year. The other gave a nebulous answer which didn't guarantee anything. And the third said he could switch at that point.</p>
