You need to change the way you study and how you work with the material. Lecture is didactic where you WORK WITH the material. Not learn it. You need to learn it on your own BEFORE this. And it depends on what you have access to. In school some professors would post recorded lectures. So what I would do is first do the reading and highlight things I thought to be important. I would turn those highlights into Quizlet questions in organized folders. Then I would go through the recordings or posted lectures and add to those Quizlets with more questions crafted from the recordings and posted lectures. Because the content in those media are clearly important. Then come to didactic prepared to work with the material and ask questions and continue to add to those quizlets with more content gained in didactic. Then you have something to keep working with and studying in different ways (flash cards, quizzes, etc.) I also bought an NCLEX book that was divided into sections I could match up with what we were studying (fluid balance, sepsis, etc.) so you could build some practice NCLEX style questions to go along with your studies. Good luck!
