<p>Would it be better for me to choose undeclared major or computer science?
If i do choose undecided, will it impact my application?</p>
<p>undecided doesn’t impact your app. </p>
<p>or at least it didn’t for me. i wasn’t ready to declare until the end of my second year.</p>
<p>(granted, it has been a few app cycles since i got into ucd, so yeah.)</p>
<p>It entirely depends on your whole application: Personal statement, GPA, SAT, ACT, Major</p>
<p>So, it is really hard to answer your question. Choose the option you feel confident on. If you talked about Computer Science in your personal statement, I’d go with declaring Computer Science. If not, I’d stick with undeclared.</p>
