Grades are universally measured variables. Regardless of different instructors teaching the same course in different sections, the final course grade is combined for all the sections representing one course. This study reflects the differences in students as they were successful in courses due to performance verse students who were not successful because of their low performance. The study used logistic regression analysis to assess students' performance in biology major courses. The findings suggest that high school GPA and high school chemistry were the predictors of students' success in entry-level biology courses. http://pubs.sciepub.com/education/2/4/1/education-2-4-1.pdf high school chemistry GPA entry-level biology
