Interested in going to graduate school I don't know where to start.

Hi everyone, I am a nursing student working on my bachelor's degree. Hopefully, I will graduate within a year. Therefore, I want to be fully prepared on what to expect when applying for a graduate program ( I am interested in being in the psychiatric nursing field but I am not sure yet). Can anyone provide me any tips or what I can do during my last year to make my application stand out ?
Keep your GPA as high as you can and network both at school and at clinic. References and a high GPA will put you on top of the pile.
