You may have been pre-enrolled in CHEM 2090 and 2091 based on your interests in Chemical Engineering, Biomedical Engineering, and/or pre-health. You may also have been pre-enrolled in CHEM 2090 and 2091 based on whether you are entering Cornell with AP Calc BC credit (students with credit for Advanced Placement Calculus can take Physics in the first semester, students without this credit cannot, as MATH 1910 is a pre-requisite for physics).

If you are a student who has already been pre-enrolled in CHEM 2090 and 2091 and you want to change your lab section, you can attempt to change this during pre-enroll or add your name and lab section preferences to the waitlist at https://chemlabs.arts.cornell.edu/waitlist.cfm.

Those students not pre-enrolled in CHEM 2090 and 2091 can try to add the course for fall during the pre-enroll period. However, if you find that the course is full, please add your name and lab section preferences to the waitlist at https://chemlabs.arts.cornell.edu/waitlist.cfm.
