LPN school issues

I'm only on my third week of nursing school (LPN) but this is hard. I've passed two checkoffs for lab already and made a 91 on the first test, so I was getting pretty excited and proud of myself but lab is getting me very discouraged. My instructor has us watch videos on multiple skills at a time and expects to just know what to do from watching the video. She yells at us for not knowing what to do. I don't understand why we don't just focus on one thing at a time.. I've been out of school for 6 years but I don't think that much has really changed. Is this just how nursing school is? I plan on working harder but after each lab I just want to go home and cry.. Please tell me it gets better..
