What can a student expect on the first day?  Nervousness is expected.  We normally speak with people before they come in so hopefully all of your questions will be answered before you come in. The instructor would introduce themselves and introduce you to a few other students.  There is no ego, there is no competition in class.  You line up in class, and we start the class.  The instructor would pair you up with someone who is good at working with new students, someone very friendly and knowledgeable.  Then you would just run through the drills with the class.  No reason to be scared or nervous.  I guarantee after the first couple minutes you will fee perfectly relaxed.
