When you are done with you first semester are you automatically enrolled in the 2nd semester or do you have to do that separately?

I am hoping to finish my 1st semester here at Penn Foster 6/15/15. When this is complete what happens next? Does it automatically kick me into the second semester? Does full tuition become due or can I keep with my automatic payments to continue? Just want to make sure I know what I need to do if there is anything. I am learning so much and  I am so excited to be finishing this semester strong
