Reading Time: 6 minutes
WGU C213 (Accounting for Decision Makers) is an Objective Assessment course covering both financial and managerial accounting — approximately 77 questions over two hours. This guide maps every competency area, explains what the OA tests in each, and links to the complete study guide and premium practice pack.
C213 is OA-only. No written PA task. The exam spans the full breadth of accounting from reading financial statements and calculating ratios to applying CVP analysis and building cash budgets — making it one of the broader OA courses in the WGU MBA program.
What Is WGU C213?
WGU C213 (Accounting for Decision Makers) develops your ability to read, analyze, and use financial information — both financial accounting (reporting to external stakeholders) and managerial accounting (supporting internal decision-making).
C213 carries 3 Competency Units. It is assessed entirely through a proctored OA — there is no Performance Assessment task. A formula sheet is available in the OA sidebar, but the exam tests conceptual application, not formula lookup.
C213 Assessment Structure
| Assessment | Format | Questions | Time |
|---|---|---|---|
| Pre-Assessment | Practice OA (unproctored) | ~77 | Self-paced |
| Objective Assessment | Proctored, closed-book | ~77 | ~2 hours |
A whiteboard and markers are permitted during the proctored OA for calculation scratch work — bring them.
The Six C213 Competency Areas
1. Nature and Purpose of Accounting
Financial vs. managerial accounting, GAAP, accrual vs. cash basis, matching concept, SOX requirements, SEC role, internal auditor functions.
Most tested: Distinguishing financial from managerial accounting, accrual basis recognition rules, SOX’s two management requirements.
2. Financial Statements
Income statement (revenue → COGS → gross profit → operating income → net income), balance sheet (assets in liquidity order = liabilities + equity, retained earnings), statement of cash flows (three sections: operating, investing, financing), journal entries (debits/credits and the accounting equation).
Most tested: Classifying cash flows into operating/investing/financing, balance sheet equation, asset ordering by liquidity, retained earnings calculation.
3. Financial Ratio Analysis
Four ratio categories — liquidity (current ratio, quick ratio), profitability (gross margin, net margin, ROA, ROE, EPS), leverage (debt-to-equity, interest coverage), and activity (inventory turnover, days in inventory, AR turnover, asset turnover).
Most tested: Calculating ratios from financial statement data; interpreting what a ratio change means for the company’s financial health.
4. Cost Systems and Cost Behavior
Variable vs. fixed vs. mixed costs, high-low method, product vs. period costs, job order vs. process costing, activity-based costing (cost pools, cost drivers, activity rates), predetermined overhead rate, over/under-applied overhead.
Most tested: Distinguishing variable from fixed costs in scenarios, applying the high-low method, ABC cost driver and rate calculation.
5. Cost-Volume-Profit (CVP) Analysis
Contribution margin per unit, CM ratio, break-even in units and dollars, target profit calculation, margin of safety, operating leverage.
Most tested: Break-even calculation, target profit units, CM ratio — these require formula application under time pressure.
6. Budgeting and Cash Flow Planning
Master budget components, production budget formula (sales + ending inventory – beginning inventory), cash budget structure (collections, disbursements, borrowing), collections grid for credit sales, direct materials/labor variance analysis (price, quantity, rate, efficiency variances).
Most tested: Cash collections grid when credit sales span multiple periods, production budget, favorable vs. unfavorable variance identification.

Why C213 Challenges MBA Students
Most WGU MBA students are not accountants. C213 assumes no prior accounting background — but covers substantial ground in two hours. The two most commonly missed areas:
1. Cash budget collections grid. When credit sales are collected across multiple periods, you must track what percentage of each month’s sales arrives in each subsequent month. Students who do not practice this specific calculation often miss multiple OA questions clustered around it.
2. CVP calculations under time pressure. Break-even, target profit, and margin of safety all use the same contribution margin foundation but require knowing which formula applies. Practicing five to ten problems until the setup is automatic is the most effective preparation.
What helps most: The “Grid System” video in the course materials for cash budgeting. The course WileyPLUS quizzes for ratio practice. A whiteboard during the OA for multi-step calculations.
C213 vs Other OA Courses
| C213 | C211 | C207 | C215 | |
|---|---|---|---|---|
| Primary domain | Accounting (financial + managerial) | Economics | Decision analysis | Operations |
| Calculator needed | Yes — CVP and ratio calculations | Moderate | Yes — EMV | Yes — EOQ |
| Whiteboard useful | Yes — cash budget grids | Less critical | Yes — decision trees | Yes — EOQ |
| Prep time (no background) | 2–4 weeks | 1–2 weeks | 1–2 weeks | 2–3 weeks |
| Most surprising topic | Cash budget collections grid | OA harder than Pre-Assessment | EMV under time pressure | Six Sigma DMAIC |
Tips for Working Adult MBA Students
Use the Pre-Assessment coaching report. C213’s coaching report is one of the most specific in the program — it identifies which competency areas need work before you sit the OA.
Study financial ratios from real financial statements. Pick any public company (Apple, Walmart, your hospital system if it publishes financials) and calculate the four ratio categories from their annual report. Applying formulas to real data cements understanding faster than practice quizzes alone.
Build the CVP formula into muscle memory. Write it out ten times: Contribution Margin = Price – Variable Cost. Break-Even Units = Fixed Costs ÷ CM. Target Profit Units = (Fixed Costs + Target) ÷ CM. After ten repetitions you will not need the formula sheet.
Practice the cash budget grid before the OA. Draw a blank grid: months across the top, collection percentages down the side. Fill it in for a sample problem. Do this three to five times until the setup is automatic.
Frequently Asked Questions About WGU C213
Does C213 have a PA task?
No. C213 is OA-only — one proctored exam is the sole assessment.
How long does C213 take?
Students with accounting backgrounds: one to two weeks. Students without accounting backgrounds: two to four weeks.
Is a formula sheet available during the OA?
Yes; in the OA sidebar. Know the formulas independently; the sidebar can glitch under exam conditions.
What is the most important formula to memorize?
Contribution Margin = Sales Price per Unit – Variable Cost per Unit. Everything in CVP analysis builds from this.
Can I retake C213 if I fail?
Yes; 14-day waiting period applies. Use the coaching report from your attempt to target specific competency gaps.
