1. Read the thread "Male Student Dillemma" currently on this Male Nursing Student thread and see what people have written. I read what you wrote in your #1 and think "good god that is such a teenage thing to do." I'm not trying to be harsh
but you have to look at this objectively: a) Yes, society judges based on appearance. Do you want to make a good impression or a negative one? Your current appearance WILL give you the latter, especially in a professional environment like Nursing school. b) Do you really think you're going to have that stuff in you when you're 36, let alone working in a hospital beforehand? Be a grown up and get rid of that stuff now.
2. Keep the jobs? You can, but your grades may suffer.
3. Can't do anything about your age but as for being the only male, how is that a problem being surrounded by girls?
If you're straight then that should be obvious. Just socialize but do NOT make moves on them. Let them do it to you if that happens. If you're gay and let them know it then if you're lucky they may come to think of you as "one of the girls" in and of itself.

<--currently reading this as an A&P refresher prior to taking TEAS in December. I like it, it's real quick and to the point. No fluff.
But, how did you get accepted to Nursing school without A&P taken already?
Tell me that, please.
5. Can't give you any, my applications will resume once I take the TEAS in December.
Nonetheless, good luck.
