To get a different Microbiology professor

We as aspiring nursing students have to deal with a lot of stress from the amount of knowledge we have to obtain. This stress should not be enhanced by one professor that makes our lives even harder by giving us an unreasonable amount of work and examine us to a point where 95% of the students have to retake the class. To retake this class, it delays the process of becoming a nursing student and makes it more expensive if we have to take it over the summer($4,000). We as aspiring Nursing majors or Biolgy majors, should have the ability to choose a different professor. One class should not determine our success in the nursing program since it is not practiced in the nursing school itself.
