I am wondering what they call exactly paper and pencil tests ? Because if is not computer test how they do to give us the result of the ATC test so quickly?
"Paper and pencil test" is just relative to the sheet of paper and pen they give us if we want to down on it some mental arithmetic ?
To those who are still "learning the material document" I found an interesting video from NATS (on their website) which explain how ATC works, I think that can help..
