I will have the BCG numerical test soon for the Milan office. Do you have any suggestions? It is not the BCG Potential Test, but one focused on numbers and logic.

Hi,

There are 2 types of BCG tests:

  1. GMAT-like test with questions similar to GMAT
  2. Online Test that is based on a case and has the questions closer to PST

If you are talking about the first test - it's just a copy of GMAT. You buy the latest GMAT Official Guide on Amazon and practice as much as possible.GMAT also has a programm that you can install on your computer with the full tests. It's important - you practice the full parts of the test with strict GMAT timing.

For the 2nd type of the test you should build the following skills:

1) Math and formulas:

  • Interest rates calculations
  • Compound margin
  • NPV using the Rule of 72, Perperuity
  • CAGR using the Rule of 72
  • Currencies exchange calculations
  • Speed, time, distance calculations
  • Equations, systems of equations
  • Ratio & Proportions
  • Solving the problems by calculating the area of the triangle
  • Profit / breakeven formula
  • Correlations, outliers (being able to spot on the graphs, tables)

2) Fast math skills

  • Rounding up and down
  • Learn how to multiply double digit numbers (google fast math tips)
  • Learn the division table up to 1/11 (i.e. 5/6 = 83.3)
  • Learn how to work with zeros (Hint: 4000000 = 4*10ˆ6)

Use math tools (Mimir math for iOS), Math tool on Viktor Cheng website to practice

3) Working with tables and graphs and deriving conclusions

  • Study "Say it with Charts" book
  • Check all available MBB presentations and publications. Practice to derive conclusions and check yourself with the actual ones from the article / presentation
  • GMAT IR part (Official guide and Manhattan prep)
  • Learn basic statistics (Any GMAT or MBA prep guides)

Good luck!

Hey,

My advice would to be for you to practise mental math (divisions, multiplications, percentages, approximations) as much as possible. This type of tests are mainly about interpretation, accuracy and speed, so you should try to be comfortable with these three dimensions.

A nice way to practise is to take a P&L from a company and start playing with their figures: e.g., what would be the % impact in profitability if transport costs decrease by X; what's the % of staff costs over revenues, etc.

Best

Hi Anonymous,

I did the non-Potential test in the Milan office some years ago (2011) and got confirmation that last year (2017) was still the same; the test consisted of two parts:

  • Numerical test. Very similar to the SHL numerical part. Paper-based, each question had 5 or 10 possible answers. Questions were not hard, but time was really short.
    • Resources: You can train online on SHL type cases with a strict time constraint. You can find an example of a SHL numerical test at the following link:

https://www.wikijob.co.uk/aptitude-test/numerical-practice

  • Logic test based on traffic lights colours. Technically speaking, the test is called Fault diagnosis. In the test, two or more traffic lights are connected by codes; each code changes a colour of the traffic light; one or more of the codes are broken and you have to understand which are the broken ones. It was a bit complex to understand the logic initially, but once understood it the test was not particular difficult.
    • Resources: You can find an example of a Fault diagnosis test at the following link:

Hope this helps,
