B.S. in Marine Biology, 2024-2025 Catalog

Four Year Degree Worksheet for: B.S. in Marine Biology - CSULB Catalog (2024-2025)

This degree worksheet is intended to help you develop a balanced course schedule while completing your degree within 4 years. The same sequence of courses (with fewer courses each semester) is also recommended for students completing their degree in 5 or 6 years.

This worksheet is not intended to replace academic advising with your assigned advisor. Students should consult with their assigned advisor to determine the appropriate sequence of required courses and electives based on their academic goals.

CSULB Enrollment Services prepares the Academic Requirements Report, which is the official graduation verification.

Major-Specific Degree Requirements

Major-Specific Degree Requirements are listed as an "MSDR" in the notes column. These courses must be completed in order to declare your major. All students must have a GPA of 2.5 or higher in the STEM MSDR suite. For more information, please see: Major-Specific Degree Requirements for CSULB Students.

Pre-Biology first-time freshmen must complete CHEM 111A and MATH 119A or higher within one year of matriculation. Some students may need to take courses during Summer Session to meet these requirements. Students who have not met the requirements by the required semester must either declare another major or meet with an Academic Advisor to determine if the student's performance in the courses merits an additional semester to complete.

Additional Notes

Students should take the Graduate Writing Assessment Requirement Placement Examination (GPE) after Year 1.

The "elective (1)" entries below are placeholders for the extra units needed for graduation if only the listed courses are taken. All students should make sure they take at least 120 units to meet graduation requirements.
