(I hope this is the right place for this post)

Hello! This is my first post. I'm am working towards applying to a DMS program in NJ, preferably UMDNJ. I would be a career changer and about 36 years old when I complete the program. My first course of action has been taking the prerequisites needed to apply to their program which include: Medical Terminology, A&P I, A&P II and Physics. I am also set up to start volunteering one day a week in the Radiology Department at our local hospital. I am looking for any advice or guidance on my course of action. I can only take the prereqs one at a time because I also work and have 2 small kids. Can anyone tell me how rewarding they find their career? Drawbacks? How do you obtain certification for first trimester screenings?  There are only handful of programs in my area (Central NJ) and 1 in Philadelphia but ALL require different prereqs to apply which is frustrating. Was the program you went to very intensive? Mine is supposed to be 15 months full time, with clinical rounds at various hospitals in the area.  I realize these programs are competitive to get into so I hope to obtain A's in my prereqs, my undergrad GPA was a 3.1.

Thank you for any information.
