You can't really call it a track day, as it will be pretty busy and varying ranges of cars and competences.
for a first visit, just take your time and do laps exactly as what you are, a learner.
enjoy the few days you are there, have a good few German beers, grab yourself a steak on a stone and come home saying you had an awesome weekend.
do not try and set lap records, don't even think of picking up a stop watch to see what times you can achieve.
there is in the region of 139 corners, a few look the same as others as you approach and its all to easy to be caught out until you really know it, and knowing it well takes far more than 10 laps over the course of a day.
ive been going now for around 9 years, probably clocked up a good few hundred laps and even now I still only class myself as moderately competent, every lap is a learning lap, laps with more experienced people always highlights something I'm still not doing quite right.
as said, take your time, and come back saying its an awesome place and you can't wait to to again
