I would second the suggestion to look at CLS as a backup. If you like and are good at Chemistry and Biology, but only pretty good at Math, this would be a better degree for keeping a high GPA than Engineering. My undergraduate degree was a BS in Medical Technology (back in the day, Clinical Laboratory Technologists were called Medical Technologists), and this would also align with your interest in pathology. Though most work in hospital clinical labs, the lab skills are valued in other areas. In addition to hospital labs, I worked at the American Red Cross and in a dairy microbiology lab at a state Department of Agriculture. Two of the med techs I worked with went on to medical school - and one did her residency in Pathology. She even continued to work as a med tech one weekend a month while in med school.
