FAQ

Common Questions Answered.

Everything you need to know about Anatomy & Physiology I — credits, grading, transfer, and how it compares to traditional options.

What is Anatomy & Physiology I?
A college-level study of human body structure and function, covering cells, tissues, and the integumentary, skeletal, muscular, nervous, and endocrine systems. It is Biology 211 with 17 chapters.
Does Anatomy & Physiology I include a lab?
No — this is the lecture course. Most nursing and allied-health programs require a lab. Pair it with Anatomy & Physiology I Lab.
Will nursing programs accept this?
Many pre-nursing tracks accept NCCRS-recommended A&P credit — and pairing this lecture with our A&P I Lab gives you the lecture-plus-lab format nursing programs expect. Your program's advisor can confirm your school's policy in minutes.
Do I need prior biology or chemistry for Anatomy & Physiology I?
No formal prerequisite. The course includes a chemistry-of-life chapter to build the needed foundation.
How is Anatomy & Physiology I graded?
Chapter quizzes, one assignment, and a cumulative final exam. 70 or above is required to pass.
How long does Anatomy & Physiology I take to complete?
58 contact hours; typically 28–30 days, though A&P is content-dense and many students take longer.
What's the difference between A&P I and II?
A&P I covers organization, support, and control systems. A&P II covers cardiovascular, respiratory, digestive, urinary, and reproductive systems.
Is there a recency limit on Anatomy & Physiology I credit?
Some health programs like sciences completed within the last 5–7 years — taking A&P now gives you a fresh completion date, and your program's advisor can confirm your school's window in minutes.
Is there a CLEP exam for Anatomy & Physiology?
No — College Board doesn't offer an A&P CLEP, so an NCCRS-recommended course like this is the main self-paced way to earn A&P credit.
What body systems does A&P I cover?
Anatomical terminology, cells and tissues, and the integumentary, skeletal, muscular, and nervous systems.
Is A&P I accepted for nursing programs?
Yes — many pre-nursing and pre-health tracks accept NCCRS-recommended A&P credit, especially as the lecture-plus-lab pair with our A&P I Lab. Your program's advisor can confirm the specifics in minutes.
Do I need the lab to get science credit for A&P I?
Most four-year and nursing programs require the lab component — pair this with the A&P I Lab course if your program needs a lab science.
Where will my college put this credit?
Usually as transfer credit, credit for prior learning (CPL), or noncollegiate/alternative credit, the same route colleges use for professional training evaluated by NCCRS. The final decision is with the university.
