What should I study for the ATI PN Pharmacology Proctored Exam?

Hi everyone,
I’m taking the ATI PN Pharmacology Proctored Exam soon, and I want to study like I’ve never seen pharmacology before. I don’t just want to memorize medications. I want to know what ATI expects students to already understand before taking the exam.

If you were starting from scratch, what would you focus on first? What topics came up the most? What drug classes and medications are the highest yield? What side effects, antidotes, lab values, and nursing interventions should I know? Are there any concepts that ATI seems to test over and over?
If you had to make a study guide for someone who knew absolutely nothing, what would you put on it?
Also, if there are any Quizlets, YouTube videos, study guides, or other resources that helped you pass, I’d really appreciate it. Thank you!
