Students interested in majoring in biological sciences are advised to apply for a major as early as possible and to consult with a CAS advisor without delay. Students must complete all required academic development and high school deficiency courses before declaring a major in biological sciences. Students are informed in writing of advisement procedures and assigned an academic advisor at the time of declaration. Students are required by the University to consult an advisor prior to registration each term.Biology – particularly specializations in medical sciences, secondary education and medical technology – requires strict course sequencing if requirements are to be completed in four years. An appointment for advisement may be made by calling the CAS Advising Office at (618) 650-5525.
