LVN interview

Hello, I have an interview this Wednesday to get into the LVN class. I am really nervous because I really really want to get into the class this September. I don't want to have to wait a whole other year and there's a lot of people trying to get into the class and they only accept about 20-25 students. Here are my questions:

1. How should I dress?

2. Should I take a resume? They didn't ask me for one. They only asked that I bring my ID, any transcripts of proof of other health related classes, and my high school diploma. Should I take a resume anyways? Do you think they will be expecting one? Or is that only for job interviews?

3. I'm pretty sure they will ask me for my strengths and weaknesses. If I say my strenght as that I adapt and learn quickly, would that sound good? Or is that stupid? And if I say my weakness is I tend to procrastinate but that I'm working on improving that, would that answer disqualify me?

4. Also, if they ask me "Tell me about yourself..." what kind of things would they be looking for? What I'm trying to say is what kinds of things should I say about myself that would interest them. Would they be interested in the schools I've attended? Or what kind of information would they be looking for with this question?

5. Lastly, do you guys have any tips or advice on how I can stand out to them so they would consider accepting me in their LVN class this year?

Please, I will greatly appreciate your responses. Oh and I've also heard handshakes are really important in situations like these. What if the person interviewing me doesn't bring his/her hand out to shake mine? Should I make the first move and ask for a handshake? Could it be that they're testing my friendly skills like that?

Haha, oh man, I'm getting all carried away aren't I? I'm just really nervous and I want to be really prepared.
