Is it normal for a research lab to have 0 undergraduate students? I'm the only undergraduate student left in the lab and I've been wanting to quit since day 1; this is my second semester and I wanted to at least make it 1 year. I'm a transfer student so I was desperate to get into a research lab asap and the advice the advisers at my university gave was to accept the first position offered because undergraduate students can't be picky. There is one PhD candidate in the lab who is notoriously condescending, who may be the reason there aren't any other undergrads in the lab anymore (along with the cutthroat dynamic within the lab itself among the post-docs/grad students). I do have thick skin thanks to having a professor who would always scold the class when we fucked up in the lab/our experiments didn't go right; my strategy to dealing with the scolding is to own up to my mistake and apologize-not sure if this is the right strategy because he then goes to tell the phd student I'm working under that I need to be supervised because I fucked something up
>I.E. leaving a reagent out that should be in 4C while I was doing an experiment; in my defense I didn't know better because nobody told me otherwise (but if I said this he would say you shouldn't need to be told, you should know better/not need your hand held as he has done in the past during my first week when I said "I'm sorry, I didn't know."

Is it acceptable for me to hop labs after gaining 1 year of experience in this lab, effectively wasting their time/resources? There has to be more enjoyable lab environments to work in.
