What question types are on the BCG Casey online case?
Structuring
You choose an approach before any maths. Our practice case asks which structure fits a coffee chain whose profit halved while sales grew; splitting profit into revenue, category margins and operating costs fits.
Reading an exhibit
You pull the right figures from a table. In our case, sandwich cost of goods rose from $18M to $33M while revenue went from $45M to $56M. That is 33 / 56 = 59% of revenue, up from 18 / 45 = 40%.
Calculation
Typed numbers on percentages, growth, margin and break-even. Example: a kiosk sells a cup at $4 and each costs $1.60 to make, so each cup contributes $2.40. With $36,000 of fixed cost, break-even is $36,000 / $2.40 = 15,000 cups.
Video recommendation
Answer first, two or three reasons with numbers, one risk, one next step, in under a minute.

How is the BCG Casey online case scored?
BCG says scoring varies by question type and each question may carry a different weight, which it does not publish. BCG also says you will not be shown your score. BCG publishes no pass mark and no pass rate, so any percentage on a prep site is unofficial.
Which BCG test will I take?
Read the name in your invitation. BCG's Mexico page lists the Online Case Experience and, for Associates, the Consulting Career Assessment (CCA) as separate steps. If your email says online case, OCE or chatbot, prepare for Casey. Which test you get depends on your office and role, and BCG publishes no rule covering everyone.
How should I prepare for the BCG Casey online case?
- Two weeks before. Open the practice case linked in your invitation; BCG says it shows the real screens.
- 10 to 4 days before. Drill percentages, margins and break-even, and practise naming the one number an exhibit answers with.
- 3 to 2 days before. Run full cases on a 35 minute clock and move on when a question drags.
- Last 2 days. Record three one-minute recommendations and watch them back.
What mistakes cost the most?
Slow early questions. You cannot go back, so lost time hurts every later question.
Rounding early. Keep full numbers to the last step.
Wrong format. Type exactly what a numeric box asks for, with the unit.
Starting the recording late. You get one take, so open the recorder with 2 minutes left.
What should I do the day before?
- Test your webcam, microphone and calculator in Chrome with the VPN off.
- Do the practice case from your invitation once.
- Pick a quiet room and a start time inside your window.
