Bain & Company South Africa Numerical/Quantitative assessment?

Hi,

I received a mail from Bain saying that I have passed the screening process and are invited to take 'the assessment' (at their offices not online). I also received an excel sheet which has formula's and macros to help me in preparing. It contained basic "market share", "percentages", and "breka-even analyses" type questions. After speaking with HR they clarified that it will be basic maltuplication/division type questions, and thats all that I could get out of them.

However, I need to know how similar the test will be to the excel they provided, or what type of questions the South-African branch typicaly ask in this 'numerical assessment'. Once I pass this only then does the case interviews begin.

Thanks for the help
