Class Characteristics

CHEM 141/142 is intended for students with only basic high school chemistry experience, or no chemistry experience at all.

Students who have had higher-level exposure to chemistry (AP, IB, honors, etc.) generally should not enroll in CHEM 141/142

Chem 143/144 is intended for students who have had an advanced high school chemistry course (AP, IB, honors, etc.). Students who have only had a basic high school chemistry course, or no chemistry experience at all, generally should not enroll in CHEM 143/144.

Why should I take these courses?

Both of these course sequences will satisfy:

1.      requirements for CHEM, BIO, MB&B, E&ES, NS&B, and SISP majors, as well as the CHEM minor.

2.      prerequisite requirements for medical/dental/veterinary schools, etc.

3.      NSM general education expectations.

When should I take these courses?

If there is any chance that you might want to major in either CHEM or MB&B, it is strongly recommended that you take these courses during your first year at Wesleyan.


There is only one laboratory course for the first-year chemistry sequence: CHEM 152. It is required for both the CHEM and MB&B majors, the CHEM minor, as well as medical schools. The course is offered in both the Fall and Spring semesters.
