Don't think it matters were you did them But for some Having a first time pass shows you'll have no trouble with type rating theory that you'll have to do thro-out your working life.
Some high end airlines may also expect to see average passes of 85%. BUT having said all that I know at least one 737 capt. who failed a paper on first attempt and is working for a small but good charter airline, so If you didn't get them all first time its not the end of the line.
