What is likely to happen when I go to court for a misdemeanor charge?

During an argument in the last snow storm I got frustrated and broke the car window of my neighbor. The day prior to the incident someone hit my car breaking the mirror and did not stop. The morning of the incident, she backed up in my car and when I went to speak to her the whole incident blew up. My husband told her he would pay but she called the police. I'm about to enter a nursing program and I don't have any prior incident with the law. I'm concern about the outcome because this could affect my application to nursing school. What should I be doing so that I don't end up with a record.
