Reddit post for context (not my words):
"No seriously. Like what's the point of having faculty advising that just gives you incorrect information? I deferred my Math 101 exam at the end of April because I was pretty sick, and was specifically told that deferring the exam wouldn't impact registration or major selection because "being able to defer an exam means that you have proved thusfar to be successful in the course as you were in good academic standing up until taking the final exam. Therefore we assume you would have been able to pass the course and get the credits."
I'm now being told by Science Advising that actually, standing deferred doesn't give you the credits for the course, because you haven't taken the exam and thus have not completed the course.
What?
I made a pretty impactful decision based off the original answer from Science Advising. If I knew that deferring an exam wouldn't enable me to register for 2nd-year math courses (and presumably, also reject my math major application since I don't have the credits for MATH 101), I would've just taken the exam sick because even if it affected my GPA, I would've at least gotten the credits for it."
