BCG does not use one single online assessment everywhere.
Some candidates receive the CCA. Some receive Casey or the Online Case Experience. In some offices, candidates receive a numerical, cognitive, or logical reasoning test instead.
This guide is for the third group: candidates whose BCG invitation mentions a numerical assessment, cognitive test, logical reasoning test, or aptitude-style online assessment.
Not sure which bucket you are in? Start with our BCG online assessment overview.
The key point is simple: this is not Casey. It is not a full case interview. It is usually a timed reasoning test designed to check whether you can process information quickly and accurately.
BCG numerical / cognitive test: quick answer
| Question | Answer |
|---|---|
| What is this test? | Office-specific aptitude assessment — numerical, verbal, and/or logical reasoning under time pressure. |
| Is it the same as CCA? | No. See the BCG CCA guide. |
| Is it the same as Casey? | No. See the Casey guide. |
| What offices mention it? | UK (numerical), Switzerland / Germany / Austria (cognitive), Nordics / Sweden (logical reasoning) — among others. |
| Main prep focus | Percentages, ratios, charts, verbal discipline, pattern recognition, speed. |
| Calculator? | Follow your invitation — some formats allow none. |
Quick answer
BCG numerical and cognitive tests vary by office, but they usually test some combination of:
- numerical reasoning
- verbal reasoning
- logical reasoning
- data interpretation
- speed and accuracy under time pressure
Some official BCG office pages describe these tests directly.
For example:
- BCG UK mentions a short numerical assessment as part of the early application process.
- BCG Switzerland describes a 30-minute cognitive test covering numerical, verbal, and logical skills.
- BCG Germany/Austria describes a 30-minute cognitive test with numerical, verbal, and logical questions, all multiple choice and without tools.
- BCG Nordics and Sweden mention a logical reasoning test with 80 questions in 30 minutes, with no calculator allowed.
So the exact format depends on the office.
Your invitation email is the source of truth.
Where this test fits in the BCG process
The test usually appears early in the process.
Depending on the office, it may happen:
- after your initial application review
- before the final CV review
- before first-round interviews
- as part of the first interview round
- alongside or before case interviews
The purpose is to add another data point before BCG spends interview time on you.
It is not trying to test whether you can run a full consulting case. It is checking whether you have the baseline reasoning skills needed for consulting work.
Is this the same as CCA?
No.
The BCG CCA is the Consulting Career Assessment. It is SHL-administered and officially described as measuring cognitive functioning and behavioral traits.
The numerical, cognitive, and logical tests covered in this article are office-specific aptitude-style assessments. Some may overlap with the CCA in the skills they test, but they are not the same thing.
A simple rule:
- If your invite says CCA or Consulting Career Assessment, read the BCG CCA guide.
- If your invite says Casey, Online Case Experience, OCE, or HireQuotient, read the Casey guide.
- If your invite says numerical assessment, cognitive test, or logical reasoning test, this guide is the right one.
What the test is likely to look like
The details vary, but the mechanics are usually straightforward.
You should expect:
- timed questions
- multiple-choice answers
- limited ability to pause
- no live interviewer
- little or no explanation after submitting an answer
- pressure from the clock
- relatively simple concepts applied quickly
The difficulty is not usually advanced math.
The difficulty is that you need to read quickly, understand the logic of the question, avoid careless mistakes, and move on.
Main question types
1. Numerical reasoning
Numerical reasoning questions test whether you can work with numbers quickly and accurately.
Common topics include percentages, ratios, growth rates, margins, averages, tables, charts, and business arithmetic.
Sample question
A company's revenue increased from $120 million to $150 million. Its costs increased from $90 million to $105 million.
What happened to profit?
A. Profit increased by $10 million
B. Profit increased by $15 million
C. Profit increased by $20 million
D. Profit stayed the same
Solution
Initial profit: $120M − $90M = $30M
New profit: $150M − $105M = $45M
Change: $45M − $30M = $15M increase
Answer: B. Profit increased by $15 million.
This is basic business math. The trap is looking only at revenue and forgetting to calculate profit.
2. Percentage and growth questions
These questions test whether you can calculate increases, decreases, and relative changes.
Sample question
A product sold 8,000 units last year and 10,400 units this year.
What was the percentage increase?
A. 20%
B. 25%
C. 30%
D. 35%
Solution
Increase: 10,400 − 8,000 = 2,400 units
Percentage increase: 2,400 ÷ 8,000 = 30%
Answer: C. 30%.
The important habit is to divide by the original number, not the new number.
3. Chart and table interpretation
These questions test whether you can find the relevant number and interpret it correctly.
Sample question
A company sells three products.
| Product | Revenue | Profit Margin |
|---|---|---|
| A | $100M | 10% |
| B | $80M | 20% |
| C | $60M | 25% |
Which product generates the highest profit?
A. Product A
B. Product B
C. Product C
D. Products B and C are tied
Solution
Product A: $100M × 10% = $10M
Product B: $80M × 20% = $16M
Product C: $60M × 25% = $15M
Answer: B. Product B.
Do not confuse revenue with profit. A bigger product is not always the most profitable one.
4. Verbal reasoning
Verbal reasoning questions test whether you can understand a short passage and identify what follows from it.
The key skill is discipline. Do not bring in outside assumptions.
Sample question
A consulting firm is reviewing a retailer's expansion plan. The retailer has strong brand awareness in its home market, but very limited recognition in the new market. The new market is growing quickly, although customer acquisition costs are high.
Which statement is best supported by the passage?
A. The retailer should not enter the new market.
B. The new market is attractive, but entry may require significant marketing investment.
C. The retailer has the same brand strength in both markets.
D. Customer acquisition costs are low because the market is growing.
Answer: B. The new market is attractive, but entry may require significant marketing investment.
The passage says the market is growing quickly, but customer acquisition costs are high. The other options either overclaim or contradict the passage.
5. Logical reasoning
Logical reasoning questions test whether you can identify patterns, rules, and relationships.
Sample question
A project code is built using three elements:
- first letter: industry (R = retail, B = banking, H = healthcare)
- second letter: region (E = Europe, A = Asia, N = North America)
- number: project duration in months
What is the code for a six-month healthcare project in Europe?
A. HE6
B. EH6
C. H6E
D. RE6
Solution
Healthcare = H · Europe = E · 6 months = 6
Order: industry → region → duration
Answer: A. HE6.
The concept is easy. The risk is rushing and mixing the order.
6. Rapid logical reasoning
Some BCG offices mention a very fast logical reasoning test. In those formats, speed matters even more than in normal aptitude tests.
Sample question
Which item does not belong?
A. 3, 6, 9
B. 4, 8, 12
C. 5, 10, 15
D. 6, 12, 20
Solution
A, B, and C follow the same pattern: first number, double, triple.
A: 3, 6, 9 · B: 4, 8, 12 · C: 5, 10, 15
D should be 6, 12, 18 — but ends with 20.
Answer: D. 6, 12, 20.
This is pattern recognition under time pressure. Spot the rule quickly and eliminate the odd one out.
7. Decision speed questions
Some logical tests are less about deep calculation and more about making fast, reasonable decisions.
Sample question
You have four tasks to complete, starting at 1:30 PM with no breaks. Which schedule works?
| Task | Duration | Rule |
|---|---|---|
| A | 45 min | Must finish before C starts |
| B | 30 min | No timing rule |
| C | 30 min | Must finish by 3:00 PM |
| D | 15 min | Must start after B finishes |
Answer choices
A. A → C → B → D
B. B → D → A → C
C. B → A → D → C
D. D → B → A → C
Option A — minute-by-minute
| Time | Task | Ends |
|---|---|---|
| 1:30–2:15 | A | 2:15 PM |
| 2:15–2:45 | C | 2:45 PM (on time) |
| 2:45–3:15 | B | 3:15 PM |
| 3:15–3:30 | D | 3:30 PM |
Answer: A. A → C → B → D — all constraints met; C finishes before 3:00 PM; D after B.
The key skill is efficient constraint checking. Eliminate D immediately (D before B). Verify the deadline on C — do not calculate every option if one already works.
How to prepare
The preparation depends on the wording in your invitation.
If the test is described as a numerical assessment, focus on percentages, ratios, profit and margin, revenue and cost, chart interpretation, tables, and speed with simple calculations. Our consulting math guide is a strong starting point.
If the test is described as a cognitive test, focus on numerical reasoning, verbal reasoning, logical reasoning, multiple-choice accuracy, and working without overthinking.
If the test is described as a logical reasoning test, focus on pattern recognition, rule identification, quick elimination, speed under pressure, and avoiding perfectionism.
What not to do
Do not prepare for this like a full case interview.
Case preparation is useful for later rounds, but it is not the same as preparing for a numerical or cognitive test.
Do not spend hours memorizing profitability frameworks if your test is a 30-minute multiple-choice reasoning assessment.
Do not try to learn advanced math. You are much more likely to need clean basics: percentage change, weighted averages, ratios, reading charts, simple logic, and fast elimination.
Timing strategy
The biggest mistake is getting stuck.
A good timing strategy:
- Read the question first.
- Identify what is being asked.
- Look only for the data you need.
- Solve cleanly.
- Eliminate impossible answers.
- Move on.
If a question is taking too long, make your best attempt and continue. In fast tests, one stubborn question can damage the whole assessment.
Calculator or no calculator?
This depends on the specific test.
Some official BCG pages explicitly say no tools or resources are allowed for cognitive or logical tests. Other BCG assessments may allow a calculator.
Follow your own invitation instructions.
If no calculator is allowed, focus on mental arithmetic and estimation. If a calculator is allowed, still practice setting up the math quickly — the calculator will not help if you do not know what to calculate.
BCG numerical / cognitive test vs CCA vs Casey
| Assessment | What it tests | How to prepare |
|---|---|---|
| Numerical / cognitive / logical test | Aptitude-style reasoning | Timed numerical, verbal, and logical practice |
| CCA | Cognitive functioning and behavioral traits | Reasoning practice plus behavioral consistency |
| Casey / OCE | Online case performance | Case math, exhibits, structuring, recommendation |
| Live case interview | Case problem solving with interviewer | Full case interview practice |
If you are unsure which one you have, check the exact wording in the invitation or read the BCG hub overview.
FAQ
Is the BCG numerical test hard?
It is usually not hard because of advanced concepts. It is hard because of timing, pressure, and accuracy.
Is the BCG cognitive test the same everywhere?
No. BCG office pages describe different formats in different geographies.
What skills does the BCG cognitive test assess?
Official BCG pages for some offices describe numerical, verbal, and logical skills.
Can I use a calculator?
It depends on the test. Some BCG office pages say no tools or resources are allowed. Always follow your own test instructions.
Is this the same as the BCG CCA?
No. There may be overlap in reasoning skills, but the CCA is a specific SHL assessment with a behavioral component.
Is this the same as Casey?
No. Casey is BCG's online case assessment with exhibits, calculations, and usually a final recommendation.
How should I prepare if I only have one day?
Focus on the basics: percentage change, profit and margin, chart reading, ratios, verbal reasoning, simple logical patterns, and timed practice. Do not try to learn everything — reduce careless mistakes and get comfortable with the clock.
Final advice
If your BCG invitation mentions a numerical assessment, cognitive test, or logical reasoning test, prepare for a timed aptitude-style assessment.
Do not confuse it with Casey. Do not over-prepare with case frameworks. Do not chase obscure math.
You need to be fast, accurate, and calm.
Practice the basics, understand the question before calculating, and keep moving.
