I recently graduated with my bachelors in biology and upon review of my transcript noticed I have earned a C in some of my larger prerequisite classes (anatomy/phys/gen chem) for PA school. I plan on retaking a few of these classes this fall as a non-declared graduate student and applying via CASPA in the spring. Is this worth my time and money? For context I work as an MA and have thousands of clinical hours, but so far 0 shadowing hours and no letters of recommendation as of yet. Any advice is appreciated :)
