"Basic science courses, such as chemistry and organic chemistry, . . . are known to students on the med-school track as 'weeder' courses. Making the grade in such courses typically determines whether someone gets into a medical school program. Those who do not survive grading curves for courses in chemistry or physics are 'weeded' out."
