Biology and chemistry are “weed out” courses almost everywhere, since they are required for pre-meds, and the pre-med process is a “weed out” process. Pre-meds skipping those introductory courses with AP credit generally need to take more advanced courses in those subject areas to meet pre-med course requirements.
This seems like a waste of time and tuition if the student is in college to learn something new. On the other hand, if the goal is to grade-grub to boost GPA for medical or law school (at the expense of actual learning), then it is understandable that some students do this.
For those who want to join fraternities or sororities, wouldn’t deferring pledging to a later semester be one way to “just do everything you can to make the first semester not so hard”?
