  • Students may not use any BIOL course as both an elective in the ENVS major and to meet course requirements for the BIOL major.
  • Students may only receive credit for POLI 348 or POLI 349, not both.
  • It is strongly recommended that all ENVS majors take GEOL 230 GIS for Geosciences.
  • It is strongly recommended that students take a statistics course before BIOL 228 Ecology.
  • Students considering graduate school are encouraged to take advanced courses in mathematics (MATH 131 Calculus and Analytic Geometry 1) and chemistry (CHEM 222 Organic Chemistry Intermediate).
  • In consultation with the environmental science faculty, students planning to attend graduate school are also encouraged to take additional courses in the sciences and participate in experiences such as internships, directed research, and field courses.
