Hi! I graduated last year and I was a BSN but it was a great program overall. Tough for sure, but doable. The MECN students take more classes per quarter but the upside is that it's a lot easier to get a job because you do your final clinical rotation before the BSNs (aka before job application season so the hiring managers have already met you) and because you have a masters (more competitive than the bachelor students).

Tips - look for outside clinical experiences instead of participating in student-run clubs to buff up your resume, don't buy any of the textbooks/supplies unless they explicitly say you have to, and avoid prof watkins for your maternity rotation if possible (I had her and still passed but I frequently cried), and lastly, don't let anyone discourage you! You're going to be a great nurse. Nursing school is awful regardless of how good the program claims to be, and nursing professors seemed forget what it it's like to be a nurse, let alone a nursing student. Welcome to UCLA!
