<p>I am really interested in stony brook, but I'm sort of intimidated by the huge class sizes. Is there any way to do a class sit in, and attend a class as a prospective student? Or do you have to be accepted before you do it?</p>
<p>Also, can you choose which class you want to attend? When do they schedule them (summer, fall only, spring only, etc.)</p>
<p>Thanks for any help!</p>
