In the Spring of their second year engineering students must choose a major at St. Lawrence. The most common options are Chemistry, Mathematics, Physics, and Computer Science. Economics, Biology, and Bio-Physics are also options. In general a student completes three years of the major as defined by the major's department and will receive their St. Lawrence degree after they complete their engineering degree.
At the time they declare their major engineering students will also choose a second adviser from their major department.
While it is possible to major in a field other than Physics, Chemistry, Mathematics, Computer Science, or Economics it requires careful planning. Practically though it can be very difficult to manage and is not advisable.
The requirements for the Engineering Combined major in Biology are:
- Biology 101 and 102 (General Biology)
- Chemistry 103 and 104 (General Chemistry).
- Six additional units of Biology. (Two of these units must be at the 300 or 400 level).
The requirements for the Engineering Combined major in Bio-Physics are:
Beginning Fall 2019 the requirements for the Bio-Physics major have changed. There are nine required courses:
