OBVIOUSLY, more capable science students and those students with stronger science backgrounds elect the more difficult science courses (i.e., Chem 6). Thus, it is not surprising that those students who have taken Nat Sci 3 do less well in Chem 20 than others. While one-fourth of those lacking the stated prerequisites for Chem 20 do lower than C-work in the course, it would be helpful to know first how that compares with other students enrolled in the course, and second, how well the other three-fourths of students without the prerequisites do. It would be especially interesting...
...advance. Perhaps some students will fail to enroll in Chem 20 at a time that would optimize their chances at gaining admission to medical school. I must agree with the Chem 20 instructors that good performance in Chem 20 is desired outcome. However, to suggest that performance in Nat Sci 3 or Chem 6 is a good indicator of projected performance in an organic chemistry course ignores both the initial factors determining who takes which introductory chemistry sequence and the backgrounds and aptitudes of those various students. While individual casea may have been leniently considered this year, permitting most students...
FRESHMEN are advised to follow carefully the placement recommendations for the various introductory chemistry sequences. Thus, if one has AP credit, either Chem 5 or Chem. 20 is appropriate. The bulk of students do not have advanced placement, however, and should elect either Nat Sci 3 followed by Chem 5 or Chemistry 6. Despite these recommendations of the Biology Department and the implicit recommendation of the Chem 20 prerequisites, Chem 6 should be elected only by students with superb math aptitude and science capacity. Chem 40a may fulfil the second half of the initial year chemistry requirement: however, Chem...
...then move up to the more difficult ones as a sophomore and beyond. While a good (B-, B) grade in a difficult course (e.g., Chem 6) is perhaps equivalent in the eyes of informed medical school admissions committees to an excellent (A-, A) grade in an easier course (e.g., Nat Sci 3), a very poor (C-, C) grade in any course of non-Herculean difficulty is a bad thing...
...freshman, enroll in Nat Sci 3 and either Math la or Math Ar unless you have been recommended for placement...
