Should I transfer?

Hi, so I've been dealing with this for awhile. For the past year I've been working full time and going to school full time. It's been hard and I was struggling with school to begin with.  I'm trying to get into my schools business program but I need  a 2.5 and I only have a 2.1 My school offers 4 grade replacements and I've used 2 already which means but I've had to retake math and will have to retake econ since I got a C instead of a C+.   
I don't really know if there's still a way for me to get into the business school if I can't get the grades I need to count for my degree.  The other thing is I'm planning to study abroad through my home university (if I can manage to save) which to me would be good because if I was abroad I wouldn't be working and my focuses would be on the culture and my academic studies. My question is,  should I try to stick it out at my current university?  If everything goes well this semester I'll have 74 credits with 46 left. 

Why do you need to work full time right now?

Can you work full time and study part time? That might be a better plan. Yes, it will take longer to finish your degree, but you would have more energy to put to studying, and your grades would be better.

If my mom gets a full time job then I can stop working full time. I am studying part time now (9 credits) first semester I’ve done part time and I’m still really struggling.
