5 classes + 1 FT job is possible ?

I am currently signing up for 4 classes in the Spring semester: MIS 410, MIS 320, OSCM 352, OSCM 435 and trying to figure it out if it's possible to go for BUS 498 because that's the only class left I need to graduate. However, I also have a 40hrs FT job so I don't know if is even possible to handle 5 classes + a job. Is there anybody used to be in this situation and is it overwhelming to balance that kind of work and study? Thank you.
