How many courses should I take for Dual Enrollment and what courses should I take for first year?

This is my first year of doing dual enrollment and Im registering for my classes.I wanted to know how many courses should I take and what courses should I take? I’m a rising senior and high school. I’m doing dual enrollment part time. I’m trying to major in business once I graduate high school. I also want to know what days should I take my college classes and what is the credit range?
