Organic Chemistry or Biochemistry for CRNA School: Which Should You Take?

We suggest taking the chemistry your target schools actually require. If both organic chemistry and biochemistry are accepted, compare your foundation, syllabus and time to earn a strong grade. Our Transcript Analyzer helps you review the chemistry you’ve already taken, and the seven-day trial includes prerequisite lessons and school research tools to help you choose the next course.

If you’ve been told to “take biochem” without anyone asking about your school list, stop before registering. The advice might fit your goals, but the course still needs a job in your actual application.

Our prerequisite course hub helps with the broader course search. For this choice, let’s look at what each school asks for and what the two subjects actually teach. A harder-sounding title won’t fix the wrong prerequisite.

What should you check in each program’s chemistry requirement?

Write the chemistry requirement beside your completed classes. Does the school need general chemistry, a second chemistry, or either organic or biochemistry? Then check credits, lab, grade and age. We suggest doing that school by school before deciding which class to add, because the same course may not serve every target.

For example, Columbia’s nurse anesthesia prerequisite page requires general chemistry plus one of organic chemistry, inorganic chemistry or biochemistry. Its current page also provides course-content descriptions and says labs aren’t required under its policy.

UTMB’s BSN-to-DNP nurse anesthesia page describes organic chemistry or biochemistry coursework with its stated recency and grade conditions. Read the current complete requirement before using the choice in your plan.

Those examples don’t settle every school. Keiser’s entry DNAP page identifies general chemistry requirements that organic chemistry or biochemistry don’t replace. Keep those subjects separate instead of assuming the higher-level title satisfies the earlier requirement.

The practical question is specific: which accepted course combination completes your target school’s requirement? Answer it before deciding which option you personally prefer.

What is the difference between organic chemistry and biochemistry content?

Organic chemistry studies organic molecules and their structure and reactions, while biochemistry focuses on chemistry in living systems, including biomolecules, enzymes and metabolic pathways. Actual course depth and prerequisites vary. Read the syllabus rather than assuming two courses with the same broad title teach the same material or carry the same academic level.

Columbia’s published content descriptions illustrate the distinction. Its organic chemistry description concerns organic molecular structure and reactivity. Its biochemistry description includes biomolecules, enzyme kinetics and metabolism. Use the descriptions as one school’s stated expectations, not a complete national curriculum.

Ask what foundation each proposed course expects. Does the biochemistry course require prior organic chemistry? Does the organic chemistry sequence require a previous general chemistry course? Your registration eligibility and learning readiness both matter.

Don’t choose solely from which subject sounds closer to anesthesia. Both contain relevant foundations, and the program requirement still controls acceptance. A personally interesting course can be a worthwhile choice after the required sequence is clear.

If you struggled with earlier chemistry, inspect why before taking the next level. A different course title doesn’t automatically supply missing foundational knowledge. Review the expected skills and choose a schedule supporting the work.

How do you compare the options across your school list?

Compare the same proposed course across the schools you would actually attend. Where is it required? Where is it an accepted option? Where do you still need to ask? We suggest keeping those answers with your school research, then comparing the course workload once you know it fits.

A planning worksheet might look like this:

• General chemistry plus an accepted second chemistry: Plan both parts of the sequence. Ask whether the exact second course qualifies.
• Organic chemistry or biochemistry: Choose one accepted option under the stated conditions. Confirm credits, level, timing and grade.
• General chemistry sequence with a lab condition: Plan the required general chemistry courses. Ask whether the proposed lab arrangement qualifies.
• Chemistry wording without enough detail: Clarify it before enrollment. Ask about subject, level, format and course equivalence.

These are examples of different requirements. Replace them with your actual schools and save where you found each answer. Then you can see which option completes the chemistry you need.

Now add the courses you’re comparing. A course might meet several targets, another only one. That’s useful information, but not the entire decision. Include workload, access, cost and whether the target list itself is realistic for your experience and other requirements.

How do you decide when both options are accepted?

If both are accepted, choose the one that fits what you need to learn and what you’re prepared to study. Read both syllabi. Does biochemistry expect organic chemistry you haven’t taken? Does one lab or exam schedule conflict with your shifts? We wouldn’t choose from a general claim that one title impresses every committee more.

Consider a hypothetical applicant with strong general chemistry preparation and an interest in molecular biology and metabolism. If the school accepts the proposed biochemistry course and she meets its prerequisites, that may be a sensible next step.

Another hypothetical applicant needs organic chemistry before enrolling in the biochemistry option available locally. Taking the prerequisite first changes the time and cost comparison. A recommendation to jump directly into biochemistry would ignore the actual course sequence.

A third applicant works nights and has two upcoming application deadlines. One accepted course has a fixed Monday-morning lab; the other has an assessment window she can use on a day off. She checks the actual dates and her foundation in the subject before choosing. “Online” or “accelerated” alone wouldn’t reveal that scheduling difference.

In each example, keep the grade goal and workload realistic. A course intended to add strong academic evidence needs enough time for learning. Don’t choose a schedule based only on the quickest possible completion date.

What if you’re choosing the course to address a low earlier grade?

Check whether the program wants a direct retake, accepts a related advanced alternative or evaluates the original prerequisite separately. A later chemistry course can add academic information without erasing the original attempt. Calculate the relevant GPA effect and verify acceptance before treating a new subject as a replacement.

Our GPA and prerequisite retake guide helps separate these questions. Keep the original grade, proposed course and current school response together.

If a program requires an acceptable general chemistry grade, biochemistry may leave that requirement unresolved. If a program explicitly accepts a comparable advanced course for its review, record the exact conditions. Don’t carry one school’s answer into every application.

Also distinguish standardized grade calculation from academic review. A later A does not automatically delete an earlier grade in NursingCAS. The new course’s effect depends on the calculation and course group used.

Strong recent performance gives you something concrete to discuss. Identify the academic gap, choose a course the school accepts, and protect the study time. Then explain what changed in how you learn and what the new work demonstrates.

What should your course-approval request include?

Provide the exact institution, course number, title, credits, level, syllabus, lab format and intended completion date. Ask whether it satisfies the named chemistry requirement and whether another course in the sequence remains necessary. A course title alone may not give the program enough information to determine equivalence.

A focused request might read:

I’m choosing between the attached organic chemistry and biochemistry courses for your ___ requirement. My completed general chemistry course is ___. Would either proposed option satisfy the requirement for the upcoming cycle? Please let me know whether the level, credits, lab format or completion date require a formal equivalency review.

Retain the answer and its conditions. If the program asks for more information, supply the specific missing item. Don’t interpret silence as acceptance or a general online-course statement as approval of an individual syllabus.

The GPA + Prerequisites lessons help organize these course decisions alongside the transcript and school list. Explore the seven-day membership trial if you want structured teaching while building the requirement-first plan.

How do you make the final choice practical?

Put registration, prerequisite courses, assignments, exams and final-grade dates on the same calendar as work and applications. Check whether the desired term is available and whether you can enroll as a non-degree student if needed. A confirmed accepted course still needs to fit the time available.

If one option requires an additional term, include that term in both cost and timing. If a lab or proctored exam creates a shift conflict, solve it before the refund deadline rather than hoping it will work out later.

Save the final course packet and program confirmation. If you later switch course numbers or providers, recheck acceptance. The earlier answer may have depended on details that changed.

Our Final Thoughts

Start with the chemistry requirement, then choose the accepted option fitting your foundation and schedule. Organic chemistry and biochemistry teach different material, and neither is a universal substitute for everything labeled chemistry.

A specific course with a verified purpose is easier to plan than a general instruction to take something harder. Get the answer first and give yourself time to learn well.
