Managerial is beating my ass

College freshman here. Finished financial accounting last semester with an A, loved it. I'm two weeks into Intro Managerial, and it's beating my ass.

Those of you that have recently taken this class (goes for higher classes like Intermediate as well) is simply reading the textbook, taking notes, and studying enough? I paid attention in the lectures but didn't thoroughly read the textbook, so i'm struggling.

I am worried for myself in the sense that Intermediate is way harder than Managerial, and Im already struggling- i do not want to cheat my way through quizzes and homework etc.

Any studying advice? words of wisdom?
