I started A&P 1 this past Monday. I have lecture Monday and Wednesday and lab on Friday. My teacher already started chapter 2 and she didn’t go over majority of chapter 1 besides a few things. I emailed her and asked if we still needed to know everything from chapter 1 that she didn’t go over. She said everything for the lecture 1 exam which is chapters 1-3 is on D2L. So am I supposed to teach myself everything she didn’t go over? I’m so scared to fail this class.
