No matter what... school/classes will take a lot of time. Nursing school is very demanding and takes lots of hours. Not just for class time... but ALSO for studying and doing intern work etc.
AND, each semester, class offerings and schedules change. Therefore, you will not always have the classes you need... only in the mornings or afternoons. So you have to realize that. The school... each semester, offers certain classes and each semester it changes. So you have to be able to change your personal schedule too... if you want to enroll in the classes required for your degree. And to therefore, graduate.
You did not say, if this job was a part-time or full time job.
Employers, some will accommodate an employee that is going to school. Some will not. ie: you cannot just not go to work, if you have a class at that time, for example. Unless the Employer is flexible....
But that is not common.
You are only in the basics of Nursing school. Now.
As you progress into the program and curriculum... know that... it will be very demanding per time needed to study and be in classes.
Aside from school schedules and work schedules... you WILL need to have lots of time.... to study. Outside of school. And studying will either be at home... or at school. So... you will also need to consider, who will babysit your children... and your Husband needs to know... that HE will need to... help a ton. As you go to school. Because, as you attend classes and the requirements for studying and internships... you will NOT be home or available. And you will need to keep up your GPA etc.
My Husband works full time and was going to school... part time. He spent ALL of his time, after work, studying, 7-days per week, night and day. AND I was like a Single Parent... for the entire time he was going to school for his degree. So.... your Husband will NEED to know... full well... what it will mean and what he will need to do... to accommodate a Spouse who will be going to school. And with the kids.
And you need to talk to your Husband... about all of this.
It also, includes him.
He will have to... be flexible in parenting/babysitting and knowing that your school/work schedule, will mean you will not be a "home Mom."
You have not been offered the job yet. And, they are not even hiring... now.
Meanwhile, you have been accepted into Nursing school and need to start that in 3 weeks. That means, you have paid for school, already.
So you need to go ahead with that.
Nursing school, takes time. But you will get your degree if you continue with it. And that will mean a job, and better pay.
