<p>I want to apply at a university in the US and currently I'm prearing for the CAE but I've read that Princeton for example doesn't recognise this exam. Should I take the IELTS too?</p>
<p>I think the most recognized exam for English proficiency here in the US is the TOEFL (Test Of English as a Foreign Language), but I could be wrong. Check into what the particular schools you're applying to accept.</p>
