I have to agree with bogey- it is a sim test not a memory test. At the start your speed and power settings will be all over the place. They expect that, if you have never flown a 777 before. What they want to see is that you are making corrections and learning so hopefully by the end of the sim you are better. That is all. They don't want somebody who can already fly a 777, they want somebody who is capable of learning and improving.
