Registration Guide: Earth & Environmental Sciences
Students majoring in Earth & Environmental Sciences will ordinarily, through coursework in the major, satisfy BU Hub requirements in Scientific Inquiry I & II; Quantitative Reasoning I & II; Diversity, Civic Engagement & Global Citizenship; Communication; Research & Information Literacy; Digital/Media Expression; and the Intellectual Toolkit. Remaining BU Hub requirements will be satisfied by selecting from a wide range of available courses outside the major or, in some cases, cocurricular experiences.
A typical first semester Earth & Environmental Sciences schedule looks like:
- CAS EE 107 Introduction to Climate & Earth System Science or CAS EE 100 Environmental Change & Sustainability
- CAS BI 107 Biology 1 (fall semester) or Calculus course or Chemistry course
- Language course or Calculus course or Course of interest
- CAS WR 120 First-Year Writing Seminar* or CAS CC 101 Core Humanities 1 (fall semester)
- Optional add-on: CAS FY 101 First-Year Seminar (fall semester) or CAS FY 102 First Year Career Development (spring semester)
*If you were previously instructed to take the Multilingual Writer Placement, please take this before registering for a course. Based on your placement, you can choose to register for one of the following courses: CAS WR 111 Academic Writing for ELL Students 1, CAS WR 112 Academic Writing for ELL Students 2, or CAS WR 120 First-Year Writing Seminar.

- If taken as IB credit, BI 107 fulfills a single requirement in each of the following: Scientific Inquiry I, Scientific Inquiry II.
-OR-
Calculus Course
Please note: you are strongly encouraged to take BI 107 as your second course. However, if you are registering in the spring, when BI 107 is not offered, or if you already have AP/IB credit for BI 107, you can consider taking a calculus course.
Earth & Environmental Sciences majors are expected to complete two calculus courses: CAS MA 123 Calculus 1 (offered either semester) and CAS MA 124 Calculus 2 (offered either semester). You should begin with CAS MA 123 unless:
-OR-
CAS CH 101 General Chemistry 1 (offered either semester): If you are registering in the spring, when BI 107 is not offered, or if you already have AP/IB credit for both BI 107 and MA 123/124, you can consider taking CAS CH 101 General Chemistry 1. (If you have an extensive high school chemistry background, you may take a higher-level chemistry course; please review General Chemistry Advising for more information about chemistry levels and recommendations.)
- If taken at BU, CAS CH 101 fulfills a single requirement in each of the following BU Hub areas: Scientific Inquiry I, Quantitative Reasoning I.
Course #3. Language Course or Calculus Course or Course of Interest
CAS Language Course: CAS students must exhibit proficiency through the fourth-semester level of a language other than English. If you have not already done so, please review the full language policy here.
If you will fulfill this requirement through coursework at BU, then your next course should be a language. If you’re new to the language, you’ll start with the first-semester level (usually coded as 111 – for example, Spanish 1 is LS 111, Arabic 1 is LY 111, etc.). If you have previously studied the language, you will need to take a placement test to determine what level to start with (for instance, LS 112 Spanish 2, LY 211 Arabic 3, LK 212 Korean 4, etc.). Please review the CAS Language Requirement page for detailed information about placement tests and appropriate levels.
If you will fulfill your language requirement through advanced credit (such as AP/IB scores) or through native proficiency of another language, you have fulfilled your language requirement and can instead take a course of interest (as seen below).
-OR-
Calculus Course
Earth & Environmental Sciences majors are expected to complete two calculus courses: CAS MA 123 Calculus 1 (offered either semester) and CAS MA 124 Calculus 2 (offered either semester). You should begin with CAS MA 123 unless:
-OR-
Course of Interest: Select a course that interests you – perhaps based on subjects you’ve enjoyed in the past or a new subject you’re excited to try for the first time! If you’re not sure where to start, you can review our Registration Instructions for tips on browsing by topic or Hub requirement.
Course #4. CAS Writing Course or Core Humanities 1
For your writing course, you will take one of the following:
- If you did not apply to BU with a TOEFL/IELTS score, you can take either:
- CAS WR 120 First-Year Writing Seminar. Each section of WR 120 focuses on a specific topic/theme, so you should register for a section that pairs with your interests.
- CAS CC 101 Core Humanities 1: Ancient Worlds: (offered Fall only): An interdisciplinary study of the origins of civilization, from Mesopotamia and the Hebrew Bible to the development of Greek civilization through Homer, Greek tragedy, and the philosophy of Plato. You should enroll in CAS CC 101 if you are considering the Core Curriculum. This course fulfills a single requirement in each of the following Hub areas: Aesthetic Exploration, First-Year Writing Seminar, Creativity/Innovation.
- If you applied to BU with a TOEFL/IELTS score, you should take the Multilingual Writer Placement (instructions will be sent via email) before you register for a writing course. The writing placement is a suggestion, but it will help you make an informed decision about the most appropriate level for you. Depending on what level WR course you register for, you will fulfill the following Hub requirements:
- CAS WR 111 Academic Writing for ESL Students 1 – fulfills The Individual in Community Hub
- CAS WR 112 Academic Writing for ESL Students 2 – fulfills Global Citizenship & Intercultural Literacy Hub
- CAS WR 120 First-Year Writing Seminar – fulfills First-Year Writing Seminar Hub (If you place into WR 120, you are welcome to take CC 101 Core Humanities 1 instead to fulfill your FYW Hub.)
Optional Course #5. First-Year Seminar
First-Year Seminar: FY 101 (offered fall only, 1 credit) – Optional
FY101 is a one-unit course that serves as a semester-long introduction to BU and college life. Each section is co-taught by a BU staff member alongside a BU student. You will meet with a small community of other incoming students who will serve as conversation partners as together you learn how to leverage BU’s resources to create a more successful and meaningful college experience. Through discussions, activities, class field trips and program-wide events, you will make immediate connections with the BU community. Specialty sections are available for natural science majors, social science majors, computer science and math majors, undeclared students, and first-generation college students. Check out the natural science sections below! Is your preferred specialty section full or unavailable? Register for a general CAS section (CAS FY101 AB-IE) where you will get to meet students from across CAS!
-OR-
First-Year Career Development Seminar: FY 102 (offered spring only, 1 unit) – Optional
FY102 will help first-year students get started on utilizing the Career Development Cycle to maximize their time at BU.
