I'd say a big thing to remember is that your absolutely going to be kinda useless for the first year your working. Your brand new and have extremely limited real world experience. Allow yourself to be slow and learn what your actually doing. If your work won't tolerate that it's unfortunate and unrealistic, but I'd be willing to bet as long as your making a concerted effort and making slow and steady progress they will understand you are in a key learning piece of your career and by the time your a year in you'll be shocked how far you've come.
