Human Biology major and CA (RA) at the same time: Doable?

<p>I'm a first year intended human biology major and as I look ahead, I'm realizing that my schedule is only going to get increasingly more demanding. I intend on applying to competitive Med schools after graduating so my grades (as well as everything else that makes me a competitive med school applicant) are very important to me. BUT, I really wanted to become a community assistant (same as RA) even though it takes up a lot of time.</p>

<p>How doable is it to be a human bio major and a CA at the same time? Answers from those with experience are appreciated.</p>

<p>Thank you in advance :)</p>
