i just completed my first set of training on the codeco system this morning

i do not know how i am ever going to get the hang of it, im just so scared of getting something wrong because everyone else seemed to be getting along fine!
i am in again tomorrow for the rest of the computer training and then the rest of the week i am shadowing. Does this mean i watch someone in their duties or do they watch me? i just kinda want to know what im goin to be doing for the rest of the week
thanks
