Do bio1b and chem 1a labs last the whole time? 4 or 5 hours or can i do back to back.

<p>and have time for food in between.</p>

<p>i strongly would not advise this. you will be a zombie by the end of the day if you do back to back labs even if bio 1b labs are sort of a joke. </p>

<p>no joke.</p>

<p>Okay, thank you so much. Also can you do upper divs if prereqs aren’t completed? is it not recommended?</p>

<p>I’m in an upper div for a breadth and its not that hard.</p>

<p>well, for example. if its mcb 102 (biochem), no that would not be a good idea because even if you somehow physically can enroll even without finishing bio 1a or ochem, you will end up getting slaughtered because some people really know their ****.</p>

<p>upper div humanities dont always need the lower divs tho if its just a general intro course. (ex: many psych upper divs will not be to hard to follow along with even if you havent taken intro to psych)</p>

<p>Okay, thanks. I was actually considering that course lol. So, is it okay if I haven’t made sure of my 2nd major? I’m taking one course in the 2nd major in the spring but if I decide to change that double major, is that okay? I’m so confused. ahh</p>
