Rather we hope you become inspired and even more determined to pursue your goal of entering the health care field. You need to have some exposure to your field of interest. Volunteer or find jobs at hospitals, nursing homes, animal shelters, anywhere you can get valuable hands-on experience. This will help you decide what you want to do and will show the admissions committees that you have tested the waters and are still committed. Likewise, the physician, veterinarian, or nurse must be able to accomplish certain activities in order to fulfill his duties.
Some schools enforce very restrictive technical standards.
Some schools are more willing to consider how disabilities can be compensated for by a given individual. It could be worthwhile for you to learn about the technical standards of some of the schools you are considering. Be prepared to explain to the admissions committee how you are going to compensate for your disability. GREs, MCATs, and VCATs are a part of the application process, and they include a test of verbal reasoning skills. Some individuals are fortunate that these tests do not present a problem.
