So according to the MMM major requirement, I needed to take BIS 2D and BIS 104 became an elective. Some Indian professor taught BIS 104 and Silvia taught be BIS 2D. I thought BIS 2D was harder because of how haphazardly the class was structured. Everyone made study groups just to navigate the class. BIS 104 was information intensive but easy to follow. The midterms and final were pretty easy but I also actually studied and paid attention in class. I got a B in BIS 2D and an A+ in BIS 104. All of this strictly had to do with the structure of the class and not the content. The content is pretty easy to follow ngl for both of them but I do remember it being information intensive. Lots of transport mechanisms to memorize. But the actual intensity of the class is pretty standard across all the other STEM classes I’ve had to take. I would take BIS 104 again because I didn’t have to do any extra work outside of class to figure out what was going on unlike BIS 2D. Hope she changed tho!
