Computer Science?

<p>I'm interested in taking a few computer science courses. I'm mainly interested in learning programming as it relates to finance and trading.</p>

<p>I have no computer science experience at all. CS 4 is full. Do you guys think CS 6 will be too hard for someone who has no CS experience? I'm actually trying not get anything below an A-. If it is too hard, should I just wait for next semester and take CS4?</p>
