Clarity on prereqs for a practicing allied health professional


I am currently a practicing speech-language pathologist and breastfeeding specialist working on preparing to apply to medical school. I completed my bachelor’s degree in SLP and an accelerated MS in SLP, with GPAs for each degree over 3.9. I am well aware that I will have to complete prerequisite courses for school and to prepare for the MCAT. However, I have heard a lot of conflicting information in various forums about what will be looked upon favorably and unfavorably by admissions committees. As a non-trad student with degrees and loans, as well as other day-to-day life expenses, there’s no way that I would be able to stop working to pursue a formal post-bacc program, due to both the cost and the scheduling. It would clearly be the most feasible for me to take a mixture of online and in-person classes through local universities and community colleges. Is this really looked upon that unfavorably? I have also been told that a M.S. in SLP degree is not looked upon as favorably as others because it is not as “rigorous;” however, SLP graduate program admissions are extremely competitive, and I have documented good grades (all A’s) from classes such as calculus, statistics, bio, A&P, and physics. Thank you for any input!
