What should I do??

I am currently going to school for patient care tech with goals of becoming an RN in the future. I recently found out that the school had lied to me among entering the program. I was told the program 12 month and now found out it is 16. We wont even have our actual graduation until 4 months after that (they do it twice a year). So here I am counting down and found out I had to add on several months. Kind of a shock to the system. Also I was worried about the externship as it is during the day and I am a single mom with a full time job, they told me they were in the works for an evening externship because they just started the evening classes recently and that by the time I have to do my externship it will be set up. Also found that is a lie. I feel like they were doing anything to get me in. I have found the same course that is only 6 weeks and am thinking of talking to the school. This would mean a hellish 6 weeks of school/work but I would be done soon and could go on with my goals or should just suck it up and deal with it. I wont be done with my current program until Nov. 7th. I go to school from 6-11p and have to get up at 4:30a for work and it's really taking a toll. I would still be working long days (school from 8-4 and then work) but it would be over soon. Advice would be welcomed!!
