UC Berkeley - Phase 1 or Phase 2 for Bio 1B?

<p>I have my phase 1 appointment today, and I can't decide whether or not I should phase 1 or phase 2 for Bio 1B. Will it fill up quickly by my phase 2? Or do you think I have a chance of getting in the class by phase 2? I think the class enrollment has expanded now, if I'm not mistaken. I would just like a second opinion please! :)</p>
