<p>Which is it? All my friends currently attending use Caltech (and in fact, deride those who spell it otherwise), but the website (and even the newletter) use Caltech, CalTech, Cal Tech, and even CIT.</p>
<p>Caltech is official, no doubt. Everything is being converted to that. CIT is sometimes acceptable but I don't like it much (and it used to stand for Carnegie Institute of Technology, what is now Carnegie Mellon). The rest are outdated.</p>
