<p>i know there are some students in L&S (specifically MCB students) that stay for more than 4 years as a student at cal (super-seniors, as they say). does CNR have a requirement where you must graduate within four years (8semesters) at cal? or is there a possibility where CNR students can stay for more than 4 years (if I need to take more grad school pre-reqs)?</p>
