WGU C908: Integrated Physical Sciences

Why Integrated Physical Sciences Sits in Almost Every WGU Program

WGU C908, Integrated Physical Sciences, is a General Education natural-science course that gives you a working survey of the physical world: matter and energy, motion and forces, chemistry, earth and space science, and a bit of astronomy. It is designed to satisfy the science requirement that shows up in many WGU degrees, so you will find students from business, IT, health, and education programs all working through the same material. You do not need a science background to succeed, which is exactly the point of the course.

Direct answer: To pass C908, study the whole breadth of topics at a conceptual level rather than memorizing details, take the preassessment to find your weak areas, and drill those with active recall and full-length practice questions until you can explain each idea in plain language. When you consistently pass practice material, schedule the objective assessment.

The reason C908 matters beyond the credit is that it teaches you to reason about evidence, interpret simple data and formulas, and connect cause and effect across physics, chemistry, and earth science. Those habits carry into later coursework and into everyday decision-making. Treat it as a chance to build genuine scientific literacy, not just a box to check, and the exam becomes far less intimidating.

What the C908 Objective Assessment Covers

C908 is assessed by a proctored objective assessment (OA) that you take online with a webcam and remote proctoring. There is no performance task or paper for this course. The questions are broad but introductory, emphasizing understanding of core concepts and the ability to apply straightforward relationships. Expect coverage across these areas:

• The nature of science and measurement — the scientific method, units, and interpreting data and simple graphs.
• Physics fundamentals — motion, forces, Newton's laws, work, energy, and basic thermodynamics.
• Chemistry basics — atomic structure, the periodic table, bonding, chemical reactions, and states of matter.
• Waves, sound, and light — the behavior of energy as it travels and transfers.
• Earth science — geology, plate tectonics, the water cycle, weather, and climate systems.
• Astronomy and the universe — the solar system, stars, and the scale and structure of space.

Because the topics span several disciplines, the challenge is breadth rather than depth. If you build a solid conceptual map of each area, you are well positioned.

How Hard Is C908, and How Long Should You Give It?

Many students report that C908 is one of the more approachable science courses at WGU, especially if you have any recent exposure to high-school-level science. The math involved is light and mostly limited to plugging values into simple formulas. That said, the sheer range of subjects surprises people who expect a single narrow topic, so do not mistake "approachable" for "no studying required."

Preparation time varies widely with your background. Students with recent science exposure often report finishing in one to two weeks of focused study, while those starting from scratch commonly describe three to four weeks of steady work. Rather than aiming for a specific number of days, use the preassessment as your gauge: when your practice scores are comfortably in passing territory, you are ready. If chemistry or physics is completely new to you, budget extra time there.

A Study Plan That Fits a Broad Survey Course

The breadth of C908 rewards a structured approach over passive rereading. Try this sequence:

1. Take the preassessment early. Do it before you feel ready. Its purpose is diagnostic — it tells you which domains need the most attention so you do not waste time on topics you already know.
2. Work section by section. Move through the course material one discipline at a time. After each section, close the book and write down the key ideas from memory. This is active recall, and it exposes gaps far more honestly than highlighting does.
3. Build a formula-and-concept sheet. Keep a running one-page reference of the handful of relationships you must know (for example, speed, force, and energy relationships) alongside definitions like element versus compound. Rewriting it from memory is itself a study tool.
4. Use spaced repetition for vocabulary. Physical science is vocabulary-heavy. Flashcards reviewed over several days lock in terms like isotope, longitudinal wave, and igneous rock without cramming.
5. Finish with full practice testing. In the final stretch, take practice questions under timed, mixed conditions so you practice switching between physics, chemistry, and earth science the way the real OA demands.

If you enjoy the chemistry portion and want to go deeper later, a course like D425 Introduction to Chemistry or C832 Chemistry with Lab builds naturally on what you learn here, and the physics section pairs well with RNT2 General Physics.

Mistakes That Trip Students Up in C908

• Going too deep on one subject. Spending days mastering advanced chemistry while ignoring earth science leaves easy points on the table. Cover everything at a reasonable level first.
• Memorizing instead of understanding. The OA often asks you to apply a concept to a new scenario, so rote memorization of a single example fails you. Learn the "why."
• Skipping the preassessment. It is the clearest signal WGU gives you about readiness. Ignoring it means studying blind.
• Neglecting the simple math. Even light calculations cost points if you have never practiced them. Do a few worked problems for motion, energy, and unit conversions.
• Confusing similar terms. Speed versus velocity, mass versus weight, and heat versus temperature are classic mix-ups. Nail the distinctions.

C908 Readiness Checklist

Before you schedule the objective assessment, make sure you can honestly answer yes to most of these:

• Can you explain the steps of the scientific method and interpret a basic data table or graph?
• Can you apply Newton's laws and describe the relationship between force, mass, and acceleration?
• Can you read the periodic table well enough to identify elements, groups, and basic atomic structure?
• Can you distinguish physical from chemical changes and describe the states of matter?
• Can you describe how waves, sound, and light transfer energy?
• Can you explain plate tectonics, the water cycle, and the difference between weather and climate?
• Can you outline the structure of the solar system and how stars form and change?
• Are you consistently passing the preassessment and any practice questions you use?

FAQ

Is C908 an OA or a PA?

C908 is assessed by a single objective assessment, a proctored exam you take online. There is no performance task, paper, or lab report to submit for this course.

Is C908 hard?

Many students consider it one of the friendlier science courses because the material is introductory and the math is light. The main difficulty is breadth — you cover physics, chemistry, earth science, and astronomy — so the key is broad, even coverage rather than deep mastery of one area.

How long does it take to finish C908?

It depends on your background. Students with recent science exposure often report a week or two of focused study, while those new to the material commonly describe three to four weeks. Let your preassessment scores, not a fixed calendar, tell you when you are ready.

Do I need to be good at math?

No. The course involves only basic calculations, such as plugging numbers into simple formulas for speed, force, or energy and doing unit conversions. If you can handle arithmetic and follow a formula, you have enough math for C908.

What is the best way to study for the exam?

Take the preassessment first to find weak spots, then work through each discipline using active recall and spaced-repetition flashcards for vocabulary, and finish with mixed, timed practice questions. Focus on understanding concepts so you can apply them to unfamiliar scenarios.

How does C908 relate to other WGU science courses?

It is a General Education survey of physical science and shares subject matter with the other natural-science offerings. If you want more depth after it, chemistry-focused courses build on the chemistry unit, and you can browse related options through the General Education hub or the full course guide index.
