>>11394580Annotate which classes reference what and bring materials from the previous course along.
In many of my classes (chemistry especially) they build upon previous knowledge, so every class is sort of connected. You're expected to actually learn what is taught rather than just cramming it for an exam...
Even less intense courses such as microbiology, for example, rely on previous knowledge. I'm in my second course for this class and knowledge of vectors and certain things given in parasitology is relevant, as well as all of the knowledge from the previous class.
You can't really accurately perform an antibiogram if you're unsure, for example, how to derive a pure culture from a human sample. You can't do organic chemistry without previous knowledge of all sorts of things such as quantum mechanics, analytical methods (volumetry, gravimetry, column chromatography), etc. Can't do physical chemistry without a solid basis in calculus, chemistry, and physics...
If you were more specific with your degree surely professionals in that field could weigh in on what is necessary to know and what isn't so necessary, but this is standard procedure in my experience.... so I'd just say get used to it, organize yourself quite well and save everything from all of your classes, current and former.
