You brain remembers thing way differently depending on whether you are actively engaged or passively watching.
If you watch a play, you kind of remember it a month later. If you are in the play you remember your lines for life. That is because you are engaged in it, waiting for a line before you can say yours, noticing little queues to help you remember things. Our simulation training is like that! You have to click on Icons, Mouse Buttons and type in the correct text in the correct order, just like in CATIA® V5, to progress. Try a sample to prove to yourself you can learn this way
