What is the BCG CCA numerical section?

BCG publicly describes the CCA as a short, multidimensional assessment but does not publish one universal numerical blueprint. Candidate reports mention numerical reasoning in some cohorts. This simulator provides original practice across four transferable families.

How does the timing work on the CCA?

Road to Offer's canonical mock uses one 12-minute countdown for eight original questions and forward-only navigation, so you rehearse the shared-budget pacing the CCA rewards before test day.

Can I prepare for the work-style portion?

Yes. Road to Offer practises both formats the assessment uses, ranking three responses and choosing between two, so neither interface is new on test day. Choose a stable recent-work reference and pick the closest description of how you actually work.

The quick version: BCG describes the CCA as a short, multidimensional assessment whose details can vary. Road to Offer's independent diagnostic uses four original Numerical tasks and four unscored work-style items on one 12-minute clock.

Why numerical setup is worth practicing

BCG's public recruiting material describes the CCA as a short, multidimensional assessment. Public BCG pages do not publish one universal vendor, section blueprint, item count, or scoring model, and candidate experiences can vary by office and cohort. Your invitation is the source of truth.

Road to Offer's independent diagnostic trains four transferable Numerical reasoning families: scheduling constraints, time reallocation, percentages and ratios, and logical patterns. It uses four scored Numerical tasks plus four unscored work-style questions on one shared 12-minute clock with forward-only navigation. The free report joins the Numerical result with a descriptive work-style reflection; full CCA access adds every walkthrough, focused practice, timed Numerical mocks, and the complete work-style library.

The full structure, scoring context, and a 4-week plan are in the BCG CCA guide.

How the simulator works

Try two verified CCA-style Numerical tasks on this page before signup. Signup resumes the same 4+4, 12-minute diagnostic at Question 3. The diagnostic then adds two more Numerical tasks and four unscored work-style questions. Sprint and Annual members and lifetime CCA Prep buyers unlock six timed Numerical mocks, focused family practice, detailed walkthroughs, progress history, and 91 original work-style familiarization items across both formats the assessment uses.

Use the numerical practice deliberately:

One sitting, clock on. Treat the eight diagnostic questions as one block. No pausing to review mid-run.
Set up before you compute. State the equation (out loud or on paper), then plug numbers. Setup errors cost more than arithmetic errors.
Use the tools in your invitation. Calculator and device rules can vary; follow the instructions for your assessment.
Review after, not during. Use the result report to identify which shape (scheduling, reallocation, quant, or logical) cost you the most seconds.

4 CCA-style practice questions

Original practice examples built around the reasoning shapes this diagnostic rewards. Solve all four inside the shared 12-minute diagnostic clock.

Example 1
Revenue rises 12% while costs rise 8% on a higher cost base. Did profit improve?
Approach
Compute the dollar change in revenue and costs separately, then compare. Comparing the percentages directly is the trap - 8% of a larger base can exceed 12% of a smaller one.
Answer
Depends on the bases: compare dollar deltas, not percentages.
Example 2
A team of 4 finishes a task in 6 days. How long for 6 people at the same pace?
Approach
Total work = 4 × 6 = 24 person-days. Divide by the new headcount: 24 / 6 = 4. Sanity-check the direction: more people, fewer days.
Answer
4 days.
Example 3
Three tasks take 3, 5, and 2 hours and share one resource. What is the minimum total time?
Approach
One shared resource means the tasks run sequentially: identify the binding constraint, sequence to avoid idle time, then add the durations. 3 + 5 + 2 = 10.
Answer
10 hours.
Example 4
A chart shows quarterly sales by region. Which region drove the year's growth?
Approach
Read the title and axes first, isolate the largest absolute delta between the first and last quarter, then connect it back to the question asked - largest delta, not largest bar.
Answer
The region with the largest absolute change, not the largest total.

4 pitfalls

4 common mistakes on the CCA numerical block

The block is short enough that one bad habit costs the whole section. These are the ones that show up most in timed reps.

Practicing untimed
Learn each question family's setup without a clock first. Once the method is stable, use the full shared countdown rather than forgiving per-question timers.
Spending 3 minutes on one question
Road to Offer's eight-question mock shares one budget. If a setup is not clear, make a structured decision and preserve time for the remaining original practice questions.
Skipping scheduling and chart questions in prep
Practice multiple transferable shapes. Use a stable read order: constraints first for scheduling; title, axes, period, and unit first for an exhibit.
Treating it like a case interview
This simulator trains numerical setup and forward decisions. Casey-style online cases and live interviews require additional structuring, interpretation, and communication practice.

Is this a realistic BCG CCA simulator?
It is independent practice, not the official assessment: 8 original questions on one 12-minute clock with forward-only navigation. The free report shows every outcome and one complete worked example; full access adds every walkthrough.
Can I prepare for the work-style portion?
Yes. Road to Offer practises both formats the assessment uses, ranking three responses and choosing between two, so neither interface is new on test day. Choose a stable recent-work reference and pick the closest description of how you actually work.
