WGU D265: Critical Thinking: Reason and Evidence
D265 is the current critical thinking course on newer WGU plans — the successor to the retired C168 — covering argument analysis, the Toulmin model, evidence evaluation, biases, and fallacies. It ends in an OA.

Build my D265 study planWhat makes it hard
The fallacy-and-bias catalog is the memorization load, and the OA presents arguments to classify rather than terms to define. The Toulmin model's parts (claim, grounds, warrant) get tested structurally, and students who learned definitions without practicing on passages misfire under time pressure.
What you'll cover
- • Argument structure and the Toulmin model
- • Deductive and inductive reasoning
- • Logical fallacies
- • Cognitive biases
- • Evaluating evidence and sources
The D265 study guide
How to study for WGU D265, step by step.
- 1
Take the pre-assessment first
Strong readers sometimes pass the PA cold. Whatever you miss almost certainly lives in the fallacy catalog or the Toulmin structure questions.
- 2
Learn the Toulmin parts on real arguments
Claim, grounds, warrant, backing — practice labeling them in actual passages, because the OA tests the structure on examples, not as definitions.
- 3
Memorize fallacies and biases with examples
Each fallacy needs a name, a definition, and a memorable example. The example is what surfaces during a timed classification question.
- 4
Classify fresh passages daily
The OA's core move is handing you an argument and asking what's wrong with it. Short daily classification practice builds the speed rereading never will.
- 5
Retake the PA, then book the OA
Most students are ready inside two weeks. A comfortable pre-assessment pass means schedule now rather than over-reviewing.

How Fennie helps with D265
Daily Plans pace D265's fallacy catalog and Toulmin units across a short schedule with classification practice built in. Fennie's flashcards hold the names; chat serves fresh arguments to classify until the OA's format feels routine.
FAQ
Is WGU D265 hard?
No — it's a gentler gen-ed. The memorization is the fallacy-and-bias catalog, and practicing classification on real passages makes the OA straightforward.
Is D265 the same as C168?
D265 is the current critical thinking course that replaced the retired C168 on newer degree plans, adding the Toulmin model emphasis. Students search both codes.
How long does D265 take?
Typically 1–2 weeks. Daily classification practice is the accelerator; passive rereading is the delay.
Pass D265 with a plan, not a cram
Upload your D265 materials and Fennie generates a Daily Plan paced to your deadline — plus chat, flashcards, and quizzes built from the actual course content.

C955 — Applied Probability and Statistics
C955 covers descriptive statistics, probability, basic data interpretation, and a light touch of algebra — it's the gen-ed math most WGU students hit first. The course ends in an OA, and the platform includes practice problem sets for every unit.
C957 — Applied Algebra
C957 is WGU's gen-ed algebra course, focused on modeling real situations with linear, exponential, polynomial, and logistic functions rather than abstract symbol-pushing. It ends in an OA and is a common companion or follow-up to C955.
C168 — Critical Thinking and Logic
C168 covers argument structure, deductive and inductive reasoning, logical fallacies, and evidence evaluation. It's a gen-ed staple across WGU programs and ends in an OA.
C100 — Introduction to Humanities
C100 surveys art, literature, music, and philosophy across major historical periods from the classical world through modernism. It's a common gen-ed requirement and ends in an OA.
