To study Biology in the School of Molecular and Cellular Biology (MCB) or the School of Integrative Biology (IB) at the University of Illinois, you apply for admission to the College of Liberal Arts & Sciences (LAS) and choose 'Biology' as your intended major. View our admission requirements.

As a freshman in Biology, you will take two introductory courses, one in the School of Integrative Biology, IB 150 (Organismal & Evolutionary Biology) and one in the School of Molecular and Cellular Biology, MCB 150 (Molecular & Cellular Basis of Life). Both of these courses consist of lectures and discussion sections, and the material covered in each course reflects the emphases of their respective Schools.

Just prior to your sophomore year, you will consult with your academic advisor and decide to complete your Bachelor's degree as a student in either the School of Molecular and Cellular Biology (MCB) or the School of Integrative Biology (IB). Many MCB and IB courses are available to students in both degree programs.

We encourage you to talk with professors and the MCB and IB Academic Advisors to learn more about yourself, your interests, your academic strengths, and the upper level courses available in your chosen major. For many students the choice is clear, but others need to spend more time exploring their options.

We invite you to visit our 'Undergraduate Studies' links above to learn more about our curricula, courses, pre-requisites, AP credit, placement tests, honors, interdisciplinary programs, research, internships, and much more.
