Questions?

Hello I have to create a test with 9 questions.
But the problem is that the outcome is based on 2 parameters.
For Example: if for the first eight questions the questions answers for the most "A" and in the 9th he answers "B" i need to send him a certain outcome. But if he answers "A" in the first 8 (as before) "C" in the 9th question the outcome must be different. Can you help me in structuring the quiz please?
