<p>I am a second-year chemical engineering major at a school that is ABET-accredited in the major. However, I understand that to be ABET-accredited, a school has to emphasize either physics or biology and my school has chosen to require four quarters of physics classes in the curriculum. They do not require any biology though. I'm still very open in what I want to go into after graduating.</p>
<p>Do many chemical engineers in this age use biology and should I take some introductory classes for it? I live in California by the way. I know that other schools require biology and some require both.</p>
