Hi,
I took the sample test, but missed a static modeling
question. Here listed are three of the questions I'm
not sure of. Please tell me if my answers are incorrect.
Thanks,
tao

20) Given the requirement statement, which of the following public methods would be used in a related sequence diagram?
a) aBalance.subtract( anAmount )
b) anAmortizationTable.calculateInterestUsing( aPayment )
