I think you need to make a plan.
You cannot “transfer” to the 4-year in the Fall because you haven’t taken pre-reqs for a major. Those pre-reqs are better done at your CC.
It means you need to find out if you can handle 1st year STEM courses.
A suggestion: this summer, rather than Calc 2, take General Chemistry and Biology1. Try to get A’s.
In the Fall, if you did well with your Summer courses, take Physics 1, Microbiology, Human Structure and Function 1 + co-requisites for these majors. Try to get As.
Reassess at this point: you can either take Chemistry 2, Physics 2, and Calculus 2+ an upper-level Psychology class and either Art or African American Studies or Women’s Studies (if you’re still planning on med school+ Physics major or biochemistry major or chem major) OR Chemistry 2, Biology 2, Human Structure&Function2, and 2 other classes - I’d recommend the same 2 as for Med School (this way you have the pre-reqs for Nursing AND you can pivot if need be).
An alternative:
Biology 1, Human Structure and Function1 over the summer - get A’s.
Fall: Microbiology, Human Structure and Function 2, Chemistry + 2 classes (as above) → Nursing admission requirements met, get into Nursing in the Spring.
Discuss all 3 plans with your Transfer Advisor.
The RN-> BSN pathway is a good one. It’s not “either one”, it’s ONE THEN the OTHER. Best of both worlds. It means you get a professional degree then a Bachelor’s degree part time or at least faster than the usual route. After a few years working as a nurse you’ll make a very comfortable salary and you’ll be able to decide whether you want to go back to graduate school to become a NP.
