Quite easy and my only A this semester that wasn't a lab. A lot more interesting than I expected too! Textbook use will help you out for a few questions but you can still get an A without. My class was online with video modules.

Pay good attention, take notes, and do a quick review of all exam material before each exam. I watched the lectures at 1.5x because he talks kinda slow but you might not have that pleasure if in-person.
