Need help

Hi everyone. This is just a throwaway account for what will become obvious reasons. Straight out of school as a new grad I got a job on the first unit that offered it, big mistake. It's PRN and I've only worked a few shifts off orientation, been here about 2 months now. Well I got offered my dream job a month ago, full time: I took it. I've wanted this job forever, before I even went to school it was something I was passionate about. I've been working it for a month and love it so much, which makes me hate the other job even more. I'm scheduled for 5 shifts in the next while. Anyways it's time for an evaluation with an educator and a manager. I was planning on quitting soon but feel bad about going in and doing this evaluation and then quitting right after. But they want to do the evaluation asap, so do I quit sooner than I wanted or fake my way through this evaluation? I don't really have anyone to talk about that's super understanding, so I thought that I would try here. Thanks in advance everyone.
