What does getting a likely letter mean?

<p>As an example, Smith College sends their own kind of LL to students.
It’s a t-shirt and a letter/package that is sent to RD applicants. It has nothing to do with athletics. It’s just a, “hey relax. It’s February and you got in” without them saying “Youre accepted!”</p>

<p>I think Yale does this too. Most schools that send LLs (separate from athletic LLs) only give them to RD applicants and send them in February.</p>
