CHEM 313 lecture is a pre- or co-requisite for CHEM 315 lab. If you previously took CHEM 313, you must have earned at least a C to use it as a pre-requisite for Chem 315. If you drop or withdraw from CHEM 313, you must also drop/withdraw from CHEM 315.  

Add, drop, and selective withdrawal deadlines can be found at

Policies for Chem 315 (grading, safety, notebook format, etc.) appear in the Lab Manual on pages 1-20. These will be supplemented by your lab instructor.  

It is the responsibility of all students to be familiar with and adhere to the GMU Honor Code.
