Generally, these service courses are for Pre-Nursing and Kinesiology majors. These students have priority during registration, as these courses are necessary for their degree programs. Once those students have filled as many seats as possible, the Biology Department will open any remaining seats to all students who meet the prerequisites (including Biology majors).

BIOL 220 Human Anatomy - BIOL 110 or BIOL 115 or BIOL 130 & 131. 
BIOL 224 Human Physiology - BIOL 110 or BIOL 115 or BIOL 130 & 131, and CHEM 115A/CHEM 115B or CHEM 125A/CHEM 125B or CHEM 110 or CHEM 105. 
BIOL 240 Medical Microbiology - (offered Spring semester only) BIOL 110 or BIOL 115 or BIOL 130 & 131, and CHEM 115A/CHEM 115B or CHEM 105.

Please note: Prerequisites do not apply to Pre-Nursing majors. For more information please contact the School of Nursing and Health Sciences.

Sometimes, when prerequisites are taken at another college, it takes a while for your transcripts to be verified and uploaded to your MySSU account. Talk to your Undergraduate or Faculty advisor and have them contact the Biology office - biology@sonoma.edu - to verify your prerequisite courses. You should also talk to your advisor about updating your Academic Requirements Report (ARR Update Form - see the Registrar's Office website).

These classes are not open to repeaters for the first several weeks of registration. This allows first-timers a chance to enroll.  At some point, the remaining seats will be open to repeaters.

  • If you received a C or better, you must complete a Course Repeat Exception form, which will require a signature from the Biology Department Chair. For more information about this form, please discuss it with your Undergraduate Advisor or your Faculty Advisor.
  • If you received a C- (minus) or lower, you can enroll once the no-repeat restriction has been lifted.
  • Please take a look at SSU's Repeat Policy. 

  1. Check this page often.
  2. Log into Class Search > Click on the live link under Class or Section > Scroll down to Enrollment Notes. You will see any restrictions and other information.
  3. Keep trying to add. At some point, you will get into the class, or on the waitlist if the section is full.

  • If you are undeclared, please make an appointment with University Advising.
  • If you are a declared major - Kinesiology, Nursing, Biology, etc - please have your faculty advisor review your course history and ARR to determine if you meet the prerequisites, or if you might need a permission code due to transfer courses. Your faculty advisor must contact biology@sonoma.edu or galtenr@sonoma.edu to request permission code.
  • Still have questions? Email biology@sonoma.edu. 

BIOL 240 Medical Microbiology is offered in the Spring semester only.
