Open Question: Is becoming a CNA and HHA a waste of time?

I'm currently going to school to become a nurse but I have to apply for the program and then get in... I have to apply in October so either way for Fall semester I'll be out of school and there is a place offering a CNA & HHA program where I can take both for $955... I want to stay in school and do something productive and I currently work at a grocery store and a bar (extremely slow) so I was hoping this would be decent employment. Do you think being a CNA/HHA is an alright job or do you think it's a waste of time to become certified?
