<p>can I just choose random subjects now, and then choose what I want to do on the day, or will they require me to do what I checklist when I register online for the test?</p>
<p>yar, except languages with listening and writing (in the past) i think. you can even add one more paper on the spot and just pay the money…</p>
<p>Yep, what woebegone said. 
Lang. with listening is available only in November, I believe…</p>
<p>Language with listening costs more too, I guess.</p>
