70-270 and 70-290 reactive??

I just recently took the 70-270 exam with a friend and after talking about it we had the same amount of questions. I've had people at work ask me if the test is "reactive", meaning if you start to answer questions wrong in one subject, the test adapts and asks you more questions in that subject. Or if you score very well, after you answer enough questions correctly for a passing grade, the exam ends (let's say 80%). I only got a couple questions wrong and I don't feel that it dug into one subject more than any other.
Does anyone know if these tests are reactive or not?
Thanks,
