Going back to school

I don't know what group to post in, so I'm posting here. Anybody have any experience on going back to school after being out of school for 3 years, with a newborn, and you are a ftm? I reeeeally want to go back to school, and the classes would start 2 months pp. I'm just nervous because its a lot of change close together! That, and I was homeschooled, so going into a classroom setting is a new experience for me altogether. Advice/suggestions/encouragement welcome!
