<p>People usually procrastinate to those times - like me. June is actually pretty common. And there's difference when you take it, just take the test whenever you are the most prepared.</p>

Most students are better off waiting until Mar or May. March has the advantage of not conflicting with Subject Tests, since they are not given in March!</p>
