<p>Everything seems idealistic right now for you since you have not even started your freshman year yet. What you want to plan for your Sophomore year may not be realistic, especially since you do not know the caliber and rigor of your classes yet And how to time manage effectively. All of your classes and schedules have to be approved by your advisor and you will be better able to get a feel for things in your spring semester of freshman year.
Things and plans change. You might want to spread things out over a winter break and summer sessions.
Yes you can take 18 credits without increasing your tuition costs, but 18 credits is a rigorous course load. It is too early to really start planning like this. It is best to develop a good working relationship with your advisor. They can give you better insight than some of us on CC. They will know the classes, professors and the general caliber of things and how it all works.<br>
Best of luck.</p>
