WGU C190: Introduction to Biology

Where Introduction to Biology Fits in Your Degree

C190: Introduction to Biology is a foundational natural science course at Western Governors University, and for most students it arrives as a general education requirement rather than a choice. It turns up across a range of degree plans, education programs especially, and in any plan that needs a life science on the transcript. It assumes nothing coming in, which is exactly why it can feel intimidating: the vocabulary is dense, the scope runs from atoms to ecosystems, and there is no partial credit for "I sort of remember mitochondria."

Direct answer: Pass C190 by treating it as a breadth-and-vocabulary exam, not a math or lab-technique exam. Work straight through the course of study once, take the pre-assessment early to expose your weak topic areas, then use flashcards and self-quizzing on those areas until you can explain each process out loud in plain language.

The good news is that C190 is assessed by a single objective assessment (OA) — a proctored, multiple-choice exam. There is no paper to write and no evaluator sending work back for revision. Everything rests on one sitting of recall and reasoning, so your whole study strategy points at one target.

The Science C190 Puts on the Exam

The course of study moves through the standard architecture of an introductory biology sequence. Expect the assessment to sample broadly across that material rather than concentrating on one favorite area:

• The nature of science and the scientific method — hypotheses, controlled variables, experimental design, and how claims get tested and revised.
• The chemistry of life — atoms, ionic and covalent bonds, water's properties, pH, and the four classes of macromolecules.
• Cell structure and function — prokaryotic versus eukaryotic cells, organelles, membranes, and transport across them.
• Energy and cellular processes — photosynthesis, cellular respiration, enzymes, and how energy moves through a cell.
• Cell division and reproduction — mitosis, meiosis, and why the difference between them matters.
• Genetics and heredity — DNA and RNA structure, replication, transcription and translation, mutation, and Mendelian inheritance.
• Evolution and natural selection — variation, selection pressure, adaptation, speciation, and the evidence behind evolutionary theory.
• Classification and biodiversity — taxonomy, the hierarchy of biological organization, and the major groups of living things.
• Ecology — biotic and abiotic factors, populations and communities, trophic levels, and nutrient cycles.

Part of that list is molecular and cellular, part is organismal and ecological, and the two halves reward different kinds of thinking. Students who enjoy one side and quietly ignore the other are the ones who get surprised.

How Hard Is C190, Really?

Many students report that C190 sits on the friendlier end of WGU's general education requirements — not because the material is trivial, but because it is familiar territory at survey depth, and a single objective assessment is a cleaner target than a written performance task. If you have taken high school biology or an anatomy course, much of this will feel like review with new labels.

The honest difficulty here is volume, not complexity. There is a great deal of terminology, and terms that sound alike — mitosis and meiosis, transcription and translation, glycolysis and the Calvin cycle — blur easily under exam pressure. Students with no science background frequently report needing more time than accelerators do, and that is normal.

On timing, student reports commonly land in the one-to-three-week range, with prior background the biggest variable. A realistic plan for someone working full time is two weeks at roughly an hour a day, plus a heavier weekend for review. Give yourself the full window rather than compressing it — biology is largely a memory task, and memory responds to repetition spread across days.

A Two-Week Plan Built Around Biology's Volume Problem

The single most effective move in C190 is to take the pre-assessment before you have finished reading everything. It feels backwards, and it works. A cold pre-assessment gives you a coaching report naming your weakest topic areas, which converts the whole syllabus into a two- or three-topic priority list. Study blind and you will spend equal time on material you already know.

Days 1–5: one full pass. Read each unit once, at a steady pace, without trying to memorize. Your only job is to build a mental map — to know that photosynthesis lives near cellular respiration and that both are about energy conversion. Take the unit quizzes as you go and note every miss.

Day 6: pre-assessment, cold. Do not cram for it. Treat the score as diagnostic data, not a verdict, and write down the weak areas it flags.

Days 7–11: active recall on the weak areas. This is where the pass is earned. Close the book and write out each process from memory: the stages of mitosis, the inputs and outputs of photosynthesis, the steps from DNA to protein. Build your own flashcards rather than using someone else's, because writing the card is half the learning. For anything that will not stick, explain it aloud as if to a ten-year-old; where you stumble is what you do not actually understand.

Days 12–13: spaced review plus practice testing. Revisit your flashcards in short sessions across both days rather than in one long block. Retake the unit quizzes and review every wrong answer until you can say why the correct option is correct and the others are not. That habit matters more than raw score.

Day 14: schedule and sit. Do a light pass over your weakest deck the morning of, then stop. Cramming new material in the final hours displaces what you already consolidated.

Two tactics are worth the extra effort. First, draw things: sketch a eukaryotic cell from memory, work a Punnett square, diagram a food web with arrows showing energy direction. Diagrams encode relationships that word lists do not. Second, group terms into contrast pairs — prokaryote versus eukaryote, dominant versus recessive, autotroph versus heterotroph. Multiple-choice items live on the boundary between two similar concepts, so study the boundary directly. The same recall-first approach carries over to C458: Health, Fitness, and Wellness, another general education course assessed by a single objective assessment.

Where C190 Students Lose Points

Memorizing definitions without mechanisms. Knowing that meiosis "produces gametes" is not enough if a question asks why crossing over increases genetic variation. Learn what each process does and why it matters, not just what it is called.

Skipping the chemistry unit. It is the section non-science students most want to avoid, and it underpins macromolecules, enzymes, and membrane transport. Skipping it costs points in three later areas, not one.

Treating the pre-assessment as a pass/fail gate. A low score there is information, not a prediction. Students who panic and reread everything from page one waste the diagnostic entirely.

Confusing the two energy pathways. Photosynthesis and cellular respiration are near-mirror images, and students routinely swap their inputs and outputs. Write both equations side by side until the direction is automatic.

Relying only on third-party flashcard decks. Shared decks online are often outdated, incomplete, or simply wrong, and many do not match your current course of study. Use the WGU course materials as your source of truth and build your own recall tools from them.

Waiting too long to schedule the OA. Booking the exam creates the deadline that makes a study plan real. Schedule it at the start of your two weeks, not after you feel ready.

C190 Readiness Checklist

• Can you identify the independent, dependent, and controlled variables in a described experiment?
• Can you name the four classes of biological macromolecules and the primary function of each?
• Can you label the organelles of a eukaryotic cell from a blank sketch and say what each does?
• Can you write the overall equations for photosynthesis and cellular respiration, and say which stores energy and which releases it?
• Can you explain how mitosis and meiosis differ, including the number and type of cells each produces?
• Can you walk from DNA to a finished protein — replication, transcription, translation — without notes?
• Can you complete a monohybrid Punnett square and predict genotype and phenotype ratios?
• Can you explain natural selection with a concrete example, including variation, selection pressure, and differential reproduction?
• Can you trace energy through trophic levels and distinguish biotic from abiotic factors?

If you can answer seven or more of those out loud without hedging, you are in good shape to sit the exam.

C190 FAQ

Is C190 an OA or a PA?

C190 is assessed by an objective assessment only — a proctored multiple-choice exam. There is no performance assessment, paper, or lab report to submit, so all of your preparation points at a single exam date.

How long does C190 take to finish?

Many students report one to three weeks of steady study, with prior biology exposure the largest factor. If science is unfamiliar territory, plan for the longer end rather than assuming you will match the fastest timelines you read about online.

Do I need a math or chemistry background for C190?

No. The chemistry in this course is introductory and conceptual — bonds, pH, macromolecules — and the quantitative work is limited to things like Punnett square ratios. If you have struggled with math before, that will not determine your outcome here.

Is there a lab component in C190?

The assessment for C190 is the objective exam, not a lab practical. Some degree plans meet their hands-on science requirement through a separate course such as C683: Natural Science Lab, so check your degree plan or the WGU institutional catalog for what your program requires.

What is the best way to study for the C190 exam?

Read the course of study once for orientation, take the pre-assessment cold to identify weak areas, then spend the bulk of your time on active recall — self-made flashcards, blank-page diagrams, and explaining processes aloud. Review the reasoning behind every miss.

How do I know when I am ready to schedule the OA?

The practical signal is being able to explain each major process from a blank page in your own words, and to say why a wrong answer is wrong rather than just recognizing the right one. If you are hovering there, schedule it; waiting for certainty adds weeks without adding readiness.

Next Steps in Your Gen-Ed Block

The recall habits you build here carry forward. If communication or systems requirements are still ahead, D268: Introduction to Communication and D459: Introduction to Systems Thinking and Applications are assessed by performance tasks rather than exams, so they need drafting time instead of a single test date. If a deeper science course is coming, D312: Anatomy and Physiology I with Lab goes further into human-body material C190 only introduces.
