A freshman completing the first term may advance his or her class year only if he or she is offered early sophomore status by the Director of the Office of Undergraduate Advising and Academic Programming. To be eligible for early sophomore status, by the end of the first term a student must have completed 25% of the undergraduate program, including an appropriate Communication Intensive subject (either a CI-H or CI-HW) and a majority of the Science Requirement subjects (mathematics, physics, chemistry, and biology). No student will be considered for early sophomore status unless he or she has completed a Communication Intensive HASS subject (CI-H or CI-HW) in the first semester.<a href=“Again,%20emphasis%20in%20the%20original,%20which%20they%20really%20seem%20to%20like.%20:”>/quote</a>)</p>
<p>My reading of this is that you must have completed at least five of the nine subjects in the science requirement (although perhaps it’s just four of the six listed, and doesn’t include REST and the lab requirement?), plus a HASS-CI. I’m not sure if there’s a units outside the GIRs requirement as well.</p>
