Im an on track student and transferring into engineering next semester. For my schedule, I have to request to get a few of the MCEN classes. How likely am I to get into these classes?

Online it states getting into these classes isn’t guaranteed, but if I don’t then I’ll genuinely be sooo far behind in my MCEN specific part of my degree which would def make things a lot harder. Hopefully I should get the classes, but does anyone know how likely that I’ll actually get into them?
