Starting my first RN job

I recently accepted a position as an ED RN. They are aware I am a new grad and I will be training for 12 weeks. I have unfortunately been out of school for about a year. I have about two weeks until I start and am looking for some advice on what are some important topics and skills I should really look over again before beginning. Thanks in advance!
Congrats! I hope to be starting a new position too soon.... I just went through vigorous interviewing last week. I also want to see what seasoned nurses have to say!
